If you can find a cheap 3.7 Intake Manifold and throttle body, This is DEFINITELY A GOOD BANG FOR BUCK PERFORMANCE MOD. Enjoy!!
Hello I been look for that Silicone coupler with the hole for the IAT sensor can you like me know where you got it from??
its a couple from P2R. Here's a link..
ebay.us/iHiCYw
Do you get idle issues after install
No issues at all, beside idle being 100-200 rpm more. It's been a couple of months now since install, and I actually havn't had any problems. This is just my experience
How much was that manifold cover and where did you buy it?
I got a 3.7 manifold with throttle body for $87 at a junkyard off a 12 TL sh-awd pretty good price, even though it’s in tuned when it gets hot can’t notice much of a difference but when it’s cold out definitely pulls Harder and better throttle response too.
it's an upgrade nonetheless, even if you dont feel the performance. car may run more efficiently also, better gas mileage with a tune. Also, if you have a typeS (3.5L) it would be less noticeable
Should I get this for my Acura tl type s 07
@@C6Elvy Yes
I love my 2005 6MT. I know what you mean about small differences being felt in these things. difference between a full and empty tank of gas is quite noticeable. i need to get the 3.7 manifold and throttle body for mine now 🤩
Lmk how it goes, I have 05 6mt too and am interested
Love the build it’s something different that a lot of people don’t do. You should dyno it and get it tuned eventually.
Thanks man, I appreciate it. Definitely wanna tune and dyno. It's in the plans
If u were on acurazine, you would see that this was a popular mod many years ago. And the problems that thecarfiend had, were already known for only the 6mt, the autos don’t have idle issues. I installed both on my 6mt type s and had idle issues. Fixed 95% of the issue by swapping the motor and throttle position sensor from a 8th gen v6 accord j35 throttle body into the 3.7 zdx throttle body. All this information is available if u dig deep enough. Fixed 100% of the idling issue after hondata. Hondata may or may not fix the issue 100% without having to replace swap throttle body parts
Good video. Nice and thorough instructions. For that connector on the throttle body, it looks like the the sensors are similar enough that you could have just pulled the sensor from your old throttle body and installed it onto the new one. That way it would connect to your harness connector without any shaving. The way you did it can work, but sometimes Honda swaps pins around in the connector between generations and causes a MIL. Glad you got it worked out.
Always passing on knowledge. Thank you for all you do. Your appreciated.
Much appreciated 🙏
Very nice indeed, I always thought that the 4th-Gen TL had the prettiest engine bay out of all Honda/Acura products. I just love how the J-series V6 engine looks in general.
But Acura took it a step forward when they developed the 4th-Gen TL. They just really wanted to make the engine the centerpiece if someone opened the hood & took a look. Kind of reminds me of how Apple develop their products… open one up & you’ll see what I mean.
I’ll take the compliment because their is no denying that the 3rd gen and especially the type s look way better than my 4th gen TL 6MT
J35 enters the chat
You realize this is the third gen right?
@@iamatlantis1 yes I do, I was comparing all the J-series V6 engine bays
You need to switch the MAP sensor and use your old one. just FYI
dang, that's one of the nicest crafted intake manifolds I've ever seen. Everything is made out of plastic nowadays.
Car looks sick. I recommend EGR valve delete to go with the manifold.
Deleting the egr smoothed out the rev hang and high idle issues for me, but I have an automatic 😢 so results may vary.
Thanks man, much appreciated. Will eventually delete EGR, more performance mods, stand alone ecu, and tune. that's the plan, slowly but surely
this will throw a CEL that you can't get rid of.. for only 2hp
@@kitvexed8229explain?
Great vid. Thanks for letting us know about the negative side of the mods. Too often we only hear about the positive.
Thank you. I like to disclose the positives and negatives. It's not all fun and games sometimes
Keep up the good work. I like how you explained the pros n cons. I daily my TL also and it's my cruiser. With gas prices the way they are, I'm keeping my TL stock. Still love her tho!
I put on an Acura 3.5 intake manifold and 3.7 throttle body on my 2003 Honda Accord V6 coupe. You should add on a P2R spacer, port/polished runners and high-flow cats. I just added those 2 things
Awesome man, that's a great upgrade for the Accord too. Full bolt on and a tune is my goal for the TL. In due time, I'm in no hurry and mod at my own pace
Why did you decide to do the 3.5 intake and not the 3.7? What’s the difference?
I’ve heard the P2R spacer doesn’t do anything tho coming from the manufacturer but if there’s a gain lmk but high flow cats are definitely worth it tho
Always a treat when yo vids pop up.
Thanks man, much appreciated 🙏
Bro... you gotta do something about those idle hands lol. Put them down every once in a while! Reminds me of Will Farrell in Talladega Nights. "I'm not sure what to do with my hands. " All jokes aside, great video. Lots of info and tips. Makes me want to get started on my 3.2 swap for a 3.5.
Funny because people always make comments about my hands in my early videos. So I actually do it on purpose now to troll you guys LOL =] I appreciate the support tho
Great build & honest review. How are the thermal gaskets working for you? I've heard of them having vacuum leak issues over time. Also, have you had additional issues since you did the swap?
I have an '05 TL-base Aspec w/ P&P IM/Runners. Been considering this build for awhile with my setup. Any feedback would be appreciated, keep up the great content! 💯
Much appreciated. I tried to document as many cons as possible in that video. So far, so good. it's been a couple of months since install, and i drive the car daily. No issues, other than 1-2 loss in MPGs. No idle issues, no vacuum leaks, nothing. But this is just my experience. If I did have issues, I would most likely swap back to the stock 3.2 IM. since winter is around the corner and I try to avoid working on the car in the snow lol. So definitely keep your stock setup when doing this mod, in case you run into issues
Don't use the thermal gasket. They warp with heat and then you get a vacuum leak, I only use OEM gaskets on my boosted motor
Can you send me the info where you got your Air Intake System. The eBay link you posted is no longer.
3.7 intake on my 3.5L, only big difference is the noise and a bit more harder pull especially with a tune
How much was the difference before the tune?
Great Job always have had a sweet spot for the 04-07 TL I had an 03 Maxima 6 speed manuel And my friend had a white 04 Tl we use to race all the time But yeah my manuel always got his Auto we always wondered How much better the manuel MT would compare to manuel 03 Maxi 😆 loved both cars - Mine was dark blue with black leather interior miss that car but now I drive a ISF thats been super reliable thanks for the video
Thanks for sharing. That sounds like an awesome race, both has close specs. Manuals are always more fun, imo. ISF is a great, reliable, and pretty fast car (Father-in-law has a Fsport RX350, super reliable and fast for what it is).
the 6MT has different gear ratios so it does pull harder for longer in each gear. also fourth gear is way better than on the auto. (based on the videos i've seen) 4th gear still weak though compared to the newer 8 speed 2.0T's. I watched a video where a nice 3.7 SH awd 2011 i think went up against a 2.0T accord, 2021, and a 2021 TLX 3.5 SH Awd. The old 2011 pulled them until fourth gear.
I think you meant "manual." I won't make the old joke about the guy named "Manuel." Happy driving.
Looks good! I have an 02 TLS that I swapped the j35 into I wanna do this intake swap next.
Totally worth it if you can find it cheap
Just passed up a white '08 TL-S manual. One of the smaller reasons i skipped it was no performance mods. This vid just came up on my FY page. Your car looks good and sounds great. Keep modding. 👌
Also, whats your MPG??? (before/after)
Much appreciated. And yeah, there's not much aftermarket support for these J-series TL's. But you'll be able to mod them nonetheless, with some creativity and skills
Hell yeah bro it looks awesome!!
I was install a throttle from Mazda rx8 to manifold from j35a8. :)
Thanks for sharing. Got myself a 3.7 from the yard. Im wondering if the MAP sensor on 3.2 fit tje 3.7.
Who ever you got that trottle body from probably moved the butterfly valve and alter the valve causing the idle to fluctuate therefore you have to do an idle re-learn. Nothing wrong with the 3.7 TB. I also feel like the oem metal gasket for the runners are better and the paper TB gasket is better I never had any idle or vacuum issues doing this mod
Excuse me bro, Can I use intake manifold and throttle body from an acura TL SH AWD 2010?
Are you saying I can install a 3.7 Intake Manifold onto a 2006 Acura MDX 3.5L?
When I did mine I used my plyers I gripped the hoses and twisted them side to side and they broke loose for others that’s don’t have a picc or scared to poke holes
What if you already have a 3.7
You gon love it when you get that tune
For sure man. I'm waiting until I get ALL my performance parts in. Then I'll get a aftermarket ECU and tune
Buenas disculpa si hay diferencia del tamaño del intake del 3.7 y el 3.2 o solo la garganta es mas grande?
Tambien el intake es mas grande y mas liviano
I've been trying to figure out if you need to get the injectors off the same car
@sebestiensoliz8831
I have a 2006 Acura MDX 3.5L. Can I swap out the Intake Manifold for a 2008 Honda Odyssey from a Mini van 3.7 Intake Manifold? And, do I have to cahnge the TB or can I use my stock TB?
You should it just put the Intake Manifold Spacer
Kinda wish my type S was a 6spd now
I know somebody with a base 6mt and another person with the type s auto.
I'll take the base all day.
Hey man, I just bid n won a 3.7L manifold with throttle body for $220 total is that a steal!!! can't wait to get it onto my 08 TLS auto.
I mean if you take the intake off of 37 do you have to take the injectors as well and get the car tuned for that...?
Nice work bro!🤌🏼
I’m surprised you needed the purge solenoid mounting bracket kit, cause I think HeelToe Auto only lists it as a necessary part for the J37 intake manifold and throttle body swap, onto the 9th gen (13-17) Honda Accord V6 (J35YX).
Great paint job!!
what are you usually supposed to do with the connector that you didn’t plug in drill a hole ? for the connector or what
Heyyyy, I know that battery hold down and that guy. Used to live in the same area. Good video though!
Yeah, Jonah is an awesome guy. He's been doing some stuff for the TL community and has his own youtube channel also
Bro, put your hands down lol
Other that that good video 👌
What cylinder heads from the Acura line that are compatible with my J35z2 2010 coupe V6 any info or suggestions are greatly appreciated
An MDX has J37 with the J35 intake manifold right? You need a J37A4 or A5 (TL SH-AWD or ZDX) to get the bigger intake manifold
Need your old sensor from the old throttle body
What is that little sleeve you have for the sensor? Where dis you get it?
Usually connectors can be disassembled and repinned. Could look into buying the 3.7 connector for that sensor (or finding one at a salvage yard for free) then replacing it on your harness. Not sure though I'm new to this. Believe it or not I'm thinking about doing this to my 1st gen Pilot lol.
Yes, they can be repinned to the correct connector. But since both connectors are very similar, and I do not have the correct one, a simple 5 minute job did the trick
@@thecarfiend11 how did you do the job? did you shave the outside of the female connector?
Are the bolts on the inside of the intake manifold gasket 10mm as well ?
yes. I reused all the bolt
I’m thinking I will just drill a hole in my 3” to 4” rubber coupler right at the throttlebody and getting a thin nut for the inside to secure in the iat sensor. Did you just push in the iat sensor in the hole? Is it secure? I think the threads on the sensor are m12/1.5 can anyone confirm this?
its a hack, but sounds like it could work. I'd be careful, because if the nut gets loose and falls off, it goes straight into the intake..
Nice but sounds like a headache specially if it’s a daily, now a days anything under 400hp ain’t nothing not worth the upgrade in my opinion.
Fair opinion, tbh. "worth" is in the eye of the beholder. I happen to run across many issues that other TL enthusiants did not. Some really do just plug and play (for the most part) and can get it for cheap at a junkyard. Horsepower isn;t the be all end all.. you can still have a fun car without 400+HP
@@thecarfiend11 it’s a beautiful car I have 02 type s and Acura integra I boosted my integra I fell I spend way more money on that b series than if I would off k swap it from the beginning
Did you install the IT sensor to silicone coupler?
yup! Didnt want the hassle of drilling or getting a new intake, etc. a bit costly, but made install super easy
What did you do to do the Brembo swap?? I want to do that to mine too
3G TL's with a manual transmission came standard with Brembo calipers in the front
What car is the IM from
Very good documentation on this topic. I've been considering this upgrade for a while. What exactly did you do to the car for the idle relearn?
I have a scan tool that I used, along with a video I followed for the idle relearn.
Scan Tool: amzn.to/3rXdKPn
Idle Relearn: ruclips.net/video/Of_llbYNwww/видео.html
If you don't have a good enough scan tool, you can always bring to a shop or dealer to get your idle relearned. Car was driveable after the install, without the relearn (for my case)
What the name of that hose at 3:39?
🫱🫲😂. Good video bro. Drive safe.
how are you bro, your acura is very beautiful, sorry I would like to make that modification to my 2007 Acura Type S, apart from just changing the manifold, did you have to do any reprogramming? Or is it just changing the manifold and throttle body? Greetings.
only thing i hate of this is you lose the cool 3.2 VTEC cover
I'll slap on a decal/vinyl 👍
Did you reuse the gaskets ?
How much horsepower does this add to the base 3.2tl?
Not sure, as I did not do any dyno before and after. Should add 5-10 Hp, in theory. Also could be even more if you add complimenting mods, like a cold air intake and intake runners
Will it pass the smog test, after its been modified like this?
Yeah, it should pass. It's not messing with exhaust or anything like that
I have the 3.0 accord will this 3.7 Intake work on it. I'm new to the honda Acura world. As far as cars go.
Not sure, you're gonna have to do your own research. If it's a J-series, it should work
Wouldn't it be easier to get a bigger throttle body, than to change the whole intake? Am i missing something?
My thoughts exactly, the two intakes looked identical in size, except the larger TB, if that's the case get the TB and an adapter?
no the j32 and 35 have a inlet ID: 67mm Outlet ID: 65mm where as the j37 has 80mm inlet and 70mm outlet. @@kevink6265
@@kevink6265 The internal diameter of the intake manifold port to the throttle body must match the internal diameter of the throttle body , else if you just use an adapter it will constrain the airflow with zero net gains.
Hey man, thanks for the detailed installation of the 3.7 manifold. I do have a question about the connector for the butterfly valve. Was it just a straight plug-in or were there any modifications done to it to plug-in?
Thank you, thank you. It was not a straight plug in. You have to shave it slightly, so it can slip on. I briefly explained it in the video
@@thecarfiend11 oh yes, I saw that. I was asking more about the butterfly valve connection that sits on the intake cover instead of the upper manifold.
Are you talking about the IAT sensor?
@@thecarfiend11 no I’m talking about the butterfly valve that sits in the upper intake to open or close depending on how much throttle is given.
Great video, thanks. Where did you get the re-manufactured Intake Manifold? I have a 2006 MDX 3.5L. Which Manifold would you recommend?
I bough mines off ebay
How did you go about the idle relearn?
I used my Bluetooth OBD2 device, and looked up a video haha
Hey brother I know a stick 3.2l has like 260hp how much hp would you say this mod added?
I didn't Dyno it, so i don't have actual results. It's estimated 5-10+ added HP/TQ. Helps when you have complimentary mods also
Where you got that rubber piece to install the sensor that it's on the 3.2 but not in the 3.7. I got everything except that rubber.
By the way great job in the painting.
Thanks
Its an intake tube for the 3.7L TL. Search up..
P2R Silicone Intake Tube Acura TLX V6 & 09-14 TL SH-AWD
Do I need to do anything to my car before making this mod? I could just virtually plug and play with some issues that come with connections or hoses
it is basically plug and play, no prerequisites required. Some people have no issues, some have issues after install.
greetings after changing the air intake you had to reprogram the computer
Hey can you share a new link for the coupler please
P2R Silicon intake tube for the 3.7 TL..

Tune required?
Not required. But it would help with gas mileage, get some more extra HP, and run better. As long as it's tuned properly
link for the intake please
KnN Cold air intake. amzn.to/49oWpSX
I have a 2007 acura tl type s would you recommend this
Only if you can find it cheap, honestly. You'll feel less of a difference in the TypeS, since its the 3.5L setup though
@thecarfriend where can I find that coupling ? Thanks
Coupler is from a 4th gen TL. P2R 3.7 intake coupler
Does it have to be from the 2011 mdx or can it come from the previous years too
Basically any Acura (of the same vintage) that has the j37 motor
Hey where did you get that coupler from? For the IAT
ebay lol. But the company that makes is P2R. its for a 4th gen TL
this is cool and all, but this ENTIRE process, intake manifold swap w/ throttle body, only gives you 5-7hp.. honestly, a spacer does the same without any of the hassle and you just put back your old cover and items like before.. P2R dynoed J37 intake on a J32A2 and it was 3whp. try getter a smaller battery or relocate it to the trunk as it overhangs centerline of the axle.. dynamically it's more improvement than this J37 swap.. this just isnt enough improvement to bother, esp for the price. I thinks everyone is caught up in the louder intake sound they think it's noticeable power, when it's really not guys.
Up to you bro 🤷♂️
@thecarfiend11 I did this same swap and it DID look better.. but the gains themselves weren't noticeable, only louder intake sounds. the battery relocated and a progress rear swaybar with lighter wheels all were better improvements 👍
Where can i find the coupler im doing the swap as well
I used this one here from P2R..
ebay.us/ZvJWd9
Did you use the j37 map sensor you need to dont use the j32 map sensor
Used J37 map sensor
Where did you get that cuppler for the sensor?
P2R 3.7 intake coupler from a 4th gen TL
Can I do this with the TLX-V6 also
I'm not 100% sure. You would have to do your own research for your specific model
Add a mdx spacer and your good to go..
for sure, in due time. Gonna add PnP runners later down the line, so I'll add the spacer next time I'm in that area
Is this legal in California?
You're gonna have to check with your laws. But it doesn't do anything with oxygen sensors, so it should be okay
So if I wanna do a engine swap what would be the best?
That's too broad of a question. I don't know much about engine swaps. But I do know.. if you got the money, time and skills, you can swap any motor into any chassis. If you're talking the 3rd gen TL's, then you can't really swap other motors without some modifications. A 3.7 motor from a newer Acura will fit into the 3rd gen engine bay, but modifications will need to be made. It's never an easy/direct swap. Knowledge is power (quite literally)
Would the 3.7 manifold fit on a 04 tl?
It's the same motor. Yes
What did u use to secure it to silicone? Super glue?
What silicon and where? I don't think I used silicon anywhere
@@thecarfiend11sry I meant the silicone coupler, how does the sensor stay in place?
I don't have anything holding it in place. It's been super tight, no clamp or zip tie needed yet
Will this swap fit on a 2003 Acura tl type s I’m new to
J series all I ever had was d series and b series and f series and there are hardly any videos on the j32s
It should be a direct swap, but don't quote me on that lol
@@thecarfiend11 lmao what’s your insta lol might be getting one soon if I need help I’ll dm u

Love the car, where did you get the coupler?
Bought off eBay. P2R 3.7 intake silicone coupler
Nice car! What wheel setup w/offset you running? Looking to get some new rims.
Thank you. My wheels are (knock-offs of Work CR Kai's) Vors TR4, Fronts: 18x8.5 +30, Rears: 18x9.5 +30. Needed spacers in the front to clear brembos

What’s the size of the coupler ?
No idea. I didn't really measure it. But I just bought a compatible 3.7 TL intake coupler and that worked out
Where can I find this throttle body or a good one compared to the stock one on a 2005 Acura tl …links don’t work anymore …thanks for helping❤
I got mine's off RockAuto.com. It's OEM refurbished. You have to know which car the Intake manifold came from, so you can get the right one (they are generally the same with the 3.2, 3.5, 3.7 but sizing may be different)
@@thecarfiend11 I see you went with the one from the rdx or was that the intake manifold?
My I.M. was from a 2011 MDX 3.7L (i believe). So I ordered the throttle body for that car, not the one for MY car.
Hey so I just did my 3.7manifold swap on a 07 base TL and ran into some problems. 3 codes popped up and after the car heats up the car will rev up to 2.5 RPM and then drop all on its own and it’s keeps doing without me pressing the accelerator
Any advice
The codes were
Po113
PO507
PO2279
try doing the idle relearn process. mine's did the same thing. could be like my situation also and be a bad throttle body. double check all lines and do the idle relearn process would be my advice
Can I do this to my 05 RL??
You would have to do your own research, but I do believe you can do this swap
how did you shave down the connector at the very end?
I literally shaved it with a blade lol. You can whip out the dremel, but found it unnecesary. only took a couple of minutes
@@thecarfiend11 for sure. Im going to try this on my 05
As someone who has a 3.5(the Accord) would this upgrade still be worth it?
Not really, the cars are pretty much maxed. These mods mostly move the power curve, less at low rpm more at wot high rpm.
If it's an auto, definitely do the MDX spacer. Adds zero net power but gives a fatter torque curve down low which is sorely needed for an auto.
Nice 👍🏾
