Nice video on the basics of an intercooler and after I removed mine to swap out some of the piping, I did notice something ... a little bit of oil in the intercooler and piping itself. What I have now is a spare OEM intercooler that I swap out every spring. The one that gets removed then gets degreased on the inside and outside (and in between the fins with a pipe cleaner). I personally think that is more efficient in the long run. I lost count of the number of larger intercoolers installed on local dubs that are so dirty ... just on the outside. I think it's safe to say that the dirt on the outside has an insulating affect (keeping heat inside) ... and any oil film on the inside prevents the air from directly contacting the aluminum surface inside. Just my 2 cents!
Hey DAP, your videos are awesome. So glad to see you guys are such hardcore enthusiasts. Just got a 2016 Golf R and looking to do an intake, LED tails, and a GIAC tune. I'll be buying my parts from you guys for sure.
Cts intercooler here !! S3 8v stage 2 , love it.
Nice. Me too
The best explanation ! Great Video !
Okay, so should I or should I not get a front mount for my gti 1.8t? GIAC X+ chip, intake and exhaust.
What's your thoughts on CTS Turbo intercooler for mk6?
Nice video with crystal clear summary, thanks!!
+GTI_CHHA Thanks glad you like!
Nice explanatory visual!!!. Agree larger intercoolers don't nessacerly gain hp but does prevent lost of power, now I claim upgrading the boost tubes much larger and intake manifold, will increase hp. I have a 6.0L powerstroke upgrading the intercooler, larger boost tubes, high flow ram intake.
Thanks for the feedback glad you like
Hello and thank you unfortunately the video,any suggestions for a good performance intercooler for my golf mk6 gti,it's stage 2 with APR filter and APR downpipe,and ECU stage 2 from APR,so what should I get for that bad boy ?
Good general information, not so good technical accuracy. There are some interesting fluid mechanic characteristics that come into play in these designs, but at that point you are just splitting hairs. You touch on a strong point though of the weight involved in these factory coolers, perhaps we should be asking if gain in power can justify the weight gain?
is it safe to put my aftermarket fmic on my audi b5 while i'm running on a stock tune and stock ko3 turbo? I plan on doing a stage 1 ecu tune by APR about a month or two down the road, but i'm curious to know if its safe to put the fmic on now before I tune the car. ps it is not my daily so i would only be driving it 2 or 3 times a week until then.
Very helpful! Thank you!
thanks for the information!! very informative.

before I had my APR stage 1 tune my engine ran really hot. Cats would live on my bonnet, with the APR tune the engine is so much cooler, I hope this translate to better performance next summer. I also would try a Cold Air intake before I ripped out the stock intercooler. Maybe less heat soak?
The stock air intake is a cold air intake as it takes air in from outside the engine bay. DAP does have an aftermarket cold air intake available which I think is,supppsed to flow more air.
I've been thinking about upgrading will it give better flow & increase exhaust sound
Very informative! I have a stock 15' GTI no PP and I was planning on updating my intercooler to the Golf R/ Audi S3. Is that the best one or are there any better Alternatives? I will be getting a tune in the near future. Much Appreciated.
+Johnn V The Golf R one is a nice if you are looking for a moderate step up that is affordable.

We also have a DIY coming on the Revo pre release intercooler which was a very nice product. We also have this unitronic one deutscheautoparts.com/mk7-gti-golf-r-intercooler-unitronic.html
Can you talk about mk1 1.9 swap wich intercooler ? And how to instal ? Please
Love DAP, but (and I may be mislead here, but this is what I have learned) a bar and plate intercooler is less efficient, but the smooth surface doesn't really gain you much in terms of "air efficiencies". Furthermore, increasing the length the air has to travel (so passenger to driver side on a golf) is actually the main issue regarding air restriction. Shortening the distance traveled nets you the largest gains (also meaning that increasing the height on a golf intercooler, if possible, won't really effect the back pressure much and is preferable). Another great benefit of after market intercoolers is the reduction in flow restriction vs. the stock units.
And for the golf I'm a huge fan (to the point where I had a custom IC/End tank setup created, but an "off the shelf" version can be bought) of the "true" front mount ic (so the intercooler is removed from the condenser/intercooler/radiator sandwich). You lose the transfer of heat and get cooler air & water temps. Great videos tho!
I really want to know what size the rims are on the white Mk 7 behind him.
well my turbo diesel have 40-50 cels starting temp and on pulls its going to 80+ what u think how much hp iam losing?
*I just like how they look like😂👌*
Hey Paul thanks for the informative video on intercoolers. Any recommendations on a performance intercooler for a MK7 Golf R running a stage 2 with a downpipe??
+Carmelo Susino Hey I would really recommend a Wagner intercooler, im running it on my MK7R with a stage 2 tune. Its the best one in my opinion
+Carmelo Susino We are going to be putting up a DIY on the Revo Intercooler we did last week. That is a really nice product which was a pre release model. We also have the Unitronic Front Mount Intercooler which is a nice product as well. deutscheautoparts.com/mk7-gti-golf-r-intercooler-unitronic.html
Will adding an intercooler allow a more aggressive tune? Like higher boost and such.
Yes.
What is the maximum power you can put through the golf R with a standard intercooler, before suffering from heat soak?
Run it hard enough on the track without cooling down, the standard intercooler will suffer from heat soak at stock power.
Can you recomend me to an inexpensive intercooler I'm not looking to race my 2020 vw gti 2.0t autobahn just want something better I had a fender bender so I'm in need of buying a interco please thanks
I have an 2015 Audi TTS 8J/ MK2. If you upgrade the intercooler will you need tuning? I’m in Florida where it’s hot. I have a stage 1 ECU tune. will having a larger intercooler with more available volume of air due to a larger size require tuning ? Would it throw off the A/F ratio or computer parameters potentially cause reliability issues without a tune?
Forgive my ignorance….
Would adding a fan to the rear of the thicker/aftermarket innercooler in stock location help ?
Yes it will help keep it cooler
I've got a bar and plate intercooler forge motorsport
I have a 2016 vw 1.8 tsi completely stock can I add a intercooler ?
Not necessarily but I guess u can.. u might get turbo lag since it takes longer to get to the engine
What are the best upgrades (besides a tune) that you can recommend for a MK6 (2013+) GLI?
Treizez34 aftermarket turbo and larger intercooler can buy a full turbo kit with the intercooler offline for like 500$ and slap it on should give u alot more hp and more boost
Down pipe n test pipe.... turbo diverter valve for turbo lag n a turbo muffler delete
thank you for mentioning that hot air have potential issues ignition inside the engine !
Raphaël Baribeau-Paquin right as you don’t want your air igniting in the engine but outside 🤦🏼♂️
i live in norway and have an original intercooler on my bmw e46 320d. normaly we have maby 1 week pr year whit over 20 celsius. is ther any point for me to opgrade my inntercooler?
Fredrik Titland if you have modified your car for ex bigger turbo maybe you have to change... If you are not a person who is looking for drag race every green light you don't have to... Bigger and more efficient intercooler would give you the same power for several floors of your foot to the gas ☺️
Thanks for the video and all the info. Quick question, I've heard that too big of an intercooler creates lag is that true I want to upgrade for my a5 2.0t b8 also for the piping whats better silcone or aluminum?
Following
Is it possible to have too big of an intercooler. And if so would it reduce the engines power
Yes if it's too big ur ganna have turbo lag
Do yo have a pdf of an operating philosophy of a tsi engine with turbo mounted to it?
Yeah stop tryna look good in the RUclips comment section
What is your opinion on using two intercoolers in a Mk7 gti? (front mount plus stock location) I've heard from one performance mechanic that its not so simple and all in all isn't ideal due to temperatures entering one and going into the second. I had considered the idea since I am stock IC with a low output APR tune. I'm not sure if even an upgraded unit will be cool enough.
+Austin Jones Answer coming on Episode 23 of the AskDAP show. Stay tuned. Be sure to subscribe
+Deutsche Auto Parts That would be much appreciated! Do it up.
Ok so intercoolers are very useful after upping the boost. Now the big question, which intercooler should we go with? Can any aftermarket intercooler work? APR for example sells theirs for a whopping $1000...is this intercooler really twice as better than the other competitors that are $100s less??
going to talk about on askdap 122
So if the air delivered to the engine have different parameters is it ok not to change the software?
depends if your software can automaticaly adjust the quantity of fuel injected, so you can keep the same afr
vincent marical every modern car’s ECU has ability to adjust for air parameters most cars from 1990s
well my turbo diesel have 40-50 cels starting temp and on pulls its going to 80+ what u think how much hp iam losing?
Should I install a performance Intercooler with a stock turbo
itslit19 thanks
just got a arm front mount for my mk6 r stage 1, havnt installed it yet but looks like a nuespeed to the tee. cant wait to see if it helps wth my iats
If I install aftermarket intercooler piping, do I have to tune my car?
Nope. It's a factor that will allow you to get more out a tune. As the engine makes more power and creates more heat, a stock intercooler could become a limiting factor because it can't dissipate the heat anymore. The return you get from a good tune is limited to the engines airflow, fuel flow, and heat dissipation. A good tune requires some mods. A good mod doesn't usually require a tune.
@@Ichibuns how do i even know if my car come with turbo production cause it have intercooler and im quite not sure if it have one
I heard wrx have water swith to spray water onto the intercooler?? Any one know about this?
BILLY BANKSTOWNER when the demi-water evaporate, it use the heat from the intercooler to do that, so it cools down. Make your hand wet and blow on it, feel the difference.
I think he has them backwards tube and fin are on most track cars
What are those wheels???
Please update video
Talking about cool air, I’d rather put water meth, what you recon?
What about water intercooler?
There's intercooler and water cooled, not water intercooler.
@@IaintTrynaGoOutLikeBIGnPAC that's what he meant
how much hp you get from ic ?
5:06
100hp
@@_Ambition124nope, 101
So then no power gain? What?? What about the company like apr or CTs claim 20 + more horsepower? Is it not true
No so what you want in an intercooler is the ability to disparate the heat soak that everyone gets quickly they call this recovering. The only way you can get more power is by the cooler making colder denser air thus tune adding more fuel for the extra air
APR claims +21 HP gain on their website
He just sold me on a cold air intake and a performance intercooler.
So you get the power back you lose due to heatsoak. So you gain power.
I know I am way late to this video, but...intercoolers DO gain power. Why? Because an intercooler increases the "Manifold Air Density". The problem with turbos is they make the intake air hot as they compress it...and hot air is less dense than cold air. To increase HP, you want to add colder air at the same boost pressure. If you only increase the boost pressure, you proportionally increase the intake air temp, which doesn't help anything. (To learn more, check out the Banks Power channel...)
True. APR says +21 hp gain on their website.
Of course they gain power!!
@@csllover Ha! I think I commented because the video kind of discouraged intercoolers?
@@fredygump5578 yes, very stange that they say this.
CTS or Unitronic
I'm confused as hell. So does that mean your car would run faster/better/produce more power in the winter time with cold air? Why are all the races happening in the summer with all that hot summer air?
Cold air makes more power but less traction.
@@Deutscheautoparts if my intercooler hose is leaking some air when i accelerate will that cause a loss in acceleration a little? my boost gauge reads 0.5 to 1 bar for just accelerating to 70 km/h at 1900 rpms. it never used to go into boost at this low speed acceleration
Can't wait to put my Wagner intercooler on my stage 2 Audi S5
Remember stock location goes between radiator and condenser is a hot sandwich What you think ?
Anyone know any good intercooler with piping under $700?
Baran MK6 esc tuning has a set with intercooler and charge pipes for about 600
BMS is like 470
Cts
@@LOUCABRASI comment was 3 years ago xD but thanks man
Is it worth the extra weight though?
If you're getting a tune for extra power, it's absolutely a necessity. Otherwise, not unless you run the living crap out of it at the track. Extended track use without a chance to cool down will cause your car to go a bit slower due to power loss.
F'king hell that was loud
I thought colder air meant more power.
wow I’ve heard the complete opposite, bar and plate are inferior
Google search specialist lol.
+laptoph4x Yes our videos do help us rank in google. Thanks for watching hope it was helpful ; ). Check out our other videos we have 182 more!
For a sec I thought he was holding a radiator
So basically they are useless unless your on a track all the time in 90 degrees weather
This is an after cooler not an intercooler, you use an intercooler with compounding turbos vs a single turbo set up it cools the air from one turbo to the next then going through the after cooler then to the intake.
Superchargers have after coolers, what are you even talking about?
The best explanation ! Great Video !
