6:30 for anyone wanting to replicate this setup, I would recommend you grab a hammer & the hole saw, then line up where you need to make the hole and tap the hole saw bit to scribe the surface of cowl. Then take a regular drill bit and drill out that scribe mark and lastly use the hole you just made to hold the hole saw in place while you make the actual four inch hole. Doing it this way should make creating that hole a lot easier.
Thank you for the detail Martin! I started my install yesterday and will finish it up today. I used a $100 3’x3.5” carbon fiber tube from silicon intakes along with 2 elbows and 4 clamps. Add the $50 aem filter and $30 4” saw bit and I’m probably $250 into it. Now I got to rebuild the stroker. . .
I made mine and wrapped it with gold reflective heat tape, as used by NASA. It’s a lot better than the silver stuff. I additionally wrapped my intake manifold in it, and wrapped my exhaust headers with exhaust wrap. Once I buy a heat gun I’ll measure it next to my buddy’s stock 1999 Cherokee and maybe make a video.
I have a 2001 Jeep Cherokee and I just put a hood scoop on my hood right over where the air filter is to get more air flow, I'm later gonna run a cold intake flow system in it, my jeep runs really great but it likes to get a little hot at times, so that's why I'm boosting my air flow, when I finish school I want to be a volunteer fire fighter and sup up my jeep, plus I drive about 90 miles every Sunday. I pastor a small country church, so I really need a good air flow in my jeep. I enjoyed your video I keep looking for the right answers but yours made a lot of since. thank you.
Companies are selling kits to do the exact same thing but they are about $800 and they are no better than your set up. Thank you for showing us how you did it
quite a few kits have been out for years. spectre is the most popular but was discontinued December of last year. no one knows why. it was a great system
On cutting the hole I have not done this exact job yet but I have done similar get a scrape piece of black abs drain pipe similar diameter to hole miter it on the end till you get the angle that Sits flush and level how you the pipe to sit then trace around it with a marker on the cowl cut it out with jig saw or tin snipes etc I use a air body saw but not everybody has one of those
The whole concept is a very good idea the only part that I don't care about is that you deleted the vibration existing rubber accordion intake I would prefer to keep that and that would make the installation more perfect
Martin, I am planning do this, but wanted your opinion on this, do you think a possible enhancement to this design would be to keep the air filter in the main tube under the hood with a Spectre "HPRO100" conical shaped filter, drill the hole in the firewall and pass the tube thru just enough say a 1/2" inch. Leave everything else alone. Since the air for the cabin comes through that area and seeing that it passes directly passed my new drilled hole, air for the engine should not be an issue. Can you give a parts no. & manufacturer for that rubber gasket you found would save a ton time tracking it all down. I like your videos please keep them coming.
That was definitely inventive. In the winter, it gets pretty cold here, so I actually put in a hot air intake to help with the miles per gallon. It helped quite a bit. Come check it out. :)
probably a good idea to thermal wrap the elbow for the throttle body to air induction tube since its above the intake/ exhaust manifold or header. you should do a video and take us for a drive so we can hear how it sounds and performs?
@@officialWWM the heat rises and then turns the air inside the "cold air intake " hot so yes all that above the intake needs to have heat resistant wrap to keep the air cool
@@MoparMan-ff8fb I understand that but the point is, the intake manifold is situated directly over the exhaust manifold, therefore, unless you are also going to insulate the intake manifold, there’s no point in worrying about the tubing. Besides, the air is travelling through the system at huge velocity, I do t it gets time to warm up. Also, the stock piping goes over the exhaust too, soooo…
@@officialWWM as long as you keep your engine RPM’s high and that fan going you create an almost air cavity that lets your vehicle live a little longer before it succumbs. It seems counter intuitive I know but it is a thing.
i don't plan on submerging my truck , but did want to know if there was any mpg gain? on some of my cars its been awesome mgp gain, on others barely 1-2mpg lol.
Well it sounds great I would want to say there was a performance improvement . Alot of things we do to our Jeeps that we hope increase performance are things that we would have to see on a dino. You can't always feel the improvement
What did you do to keep rain water from pouring down into your air intake ...It might not be an issue in the Dry west but in the northeast it's a huge issue ?
@@benthebuilder6934 the hole that gets covered, yeah I saw it. I also see cherokees with this done to them all the time at yearly cherokee events, with little to no issue
@@TheOceanX he cut the cowl out above the rectangle hole, if you read his other replies he said water gets on the filter but hasn't been a problem for him.
Isabeau Touchard I've driven this vehicle in some pretty good downpours and it has never even given me a little bit of a hiccup if anything it's only drawing in some water vapor which doesn't hurt anything at all. you're basically steam cleaning your engine
I see that you have got a good alternative to a hood scope. What is that called? It probably have almost like an intercooler effect with those and the pipe running from the snorkel :)
Martin...Great project and video. Exactly what I was hoping to find. Is all of the tubing EMT? Where'd you get the 90s and heat wrap? How about a parts list? Thanks. Gene
What size is the 90 on the throttle body side? It’s definitely not 3 inch. For anyone else wondering, a 2.25 inch to 3 inch is too small. I’m gonna try a 2.5 inch to 3.0 inch next and will update so you don’t have to waste your money too.
@@officialWWM In addition to the wiper motor being in the way, that’s also the side with the cowl intake in it. (As in where the air normally enters the cowl in order for the cabin to have air) The vents on the passenger side (Right side) are faux, and thus cannot let rain pour directly onto the intake.
@@officialWWM assuming that your wiper motor and cowl intake are on your drivers side (right side), you are able to take the direct route to the firewall you mentioned and will have a much more efficient cold air intake than most of us.
@@TheOceanX thanks for the tips, I actually just finished building one. I was able to take a pretty much direct route back from the throttle body to the firewall. It was really very simple and seems to work great. I now have an extra battery where the air box used to be :)
Being that the filter is mounted horizontal the rain will run through the filter from one side through to the other when you're driving you are gonna pull in a little bit of water it's more of a mist and if anything it's steam cleaning the inside of your combustion camber. I have driven in some heavy rains over the years and never have had a problem.
+TruthWarriorFilms I did have one on my Cherokee. It was on there when I bought it. I personally don't think there wroth it. I would do a 60 or 62mm throttle body and a true cold air intake and forget about the spacer.
The only time you hear it is on a cold start up you'll get a bit of a hissing sound but it goes away within a couple minutes depending on the ambient temperature.
Go to your engine bay under your airbox. In that area you should find a wiring harness and coupler. Mine was half melted down and corroded all to hell. Made a serious ground loop too, and blew my instrument cluster light fuse, radio fuse, headlight relay, horn fuse... All sorts of crap. First place I'd look. If that's the case carefully cut one wire on the harness, cut the corresponding wire on the other side, solder them together, black tape wrap them, and keep repeating that until all of the wires have been cut and hard wired. Hope this helps.
Got wires rubbing somewhere, or melted wiring. But its endless. What I did is took a meter to the wiring behind the pull light switch and btw it's a tight fit so it's a pain in the butt. But the wire was loose inside the housing of the wiring harness. Also the fins that stick out might need to be bent to touch the wires right. After a while they get loose and whatever. My xj is a 96
+Karo Staro That side of the cowl is not open to the outside, just the drivers side, you actually have to fill that whole cowl to the point water is pouring into the interior before that cowl intake would start sucking water. This is a great way to keep from sucking water into your intake!!!!! - oh I see he removes the covering on that side - not good.
+Bryan Webster I have driven this thing in the rain many times and never have had a problem. just remember when its parked water runs through the air filter not down the intake. and when you're driving it so what if it sucks a little bit of water. you're talking water vapor.

This makes it extremely loud inside the cab. Every time you open the throttle it sounds like your registration is going to get sucked through the glove box. Also it looks pretty ghetto. The guy I bought my XJ from had made one and I called it the crack pipe until I reinstalled the OEM airbox from a junkyard.
if you have that cowl plastic piece cut off and taken out that opens it up to the elements. For example what's stopping water from hitting the top of that air filter? you also have hood vents to release heat from the engine bay which is in turn being sucked in through the opening to the elements through the air intake filter and back into your engine. how is this a cold air intake system please explain?
Kelby Braggs yes water does hit the top of the filter but that doesn't really matter as it also will run through the filter through the bottom side of the filter so water does not directly enter the intake tube only when the engine is running does run water run into the engine and this would be water vapor. Driving in the rain many times and you cannot even tell any difference from when it's not raining.
When the engine is not running the water is simply going to run through the filter from one side to the other not down the intake. And when the engine is running I would imagine it does suck a little bit of water I have never had a problem and it is more like steam cleaning the combustion chamber.

how crazy is it to do this with a 2013 mustang. i got a cowl hood
What size is the end of the 90* coupler that connects to the throttle body?
What are the dimensions of the blue elbow at the throttle body?
Hey Martinbuilt I love the video. My question with this build is have you noticed any fuel economy gain or power gain?
A bit of a pain to clean the air filter .. But I like the Idea of true cold air !!

uvha X I just think the Spectre has a small filter. but I like the idea or design.
If you remove the factory cowl grill, doesn't that let rain water fall directly on your filter? I left mine on in that section.
I've driven in the rain with no ell affix. When the engine is not running rain water just passes threw the filter. I haven't had any problem.
That was definitely inventive. In the winter, it gets pretty cold here, so I actually put in a hot air intake to help with the miles per gallon. It helped quite a bit. Come check it out. :)

what bout the noisy? is it loud since its is cowl set up instead of factory air box
The only time you hear it is on a cold start up you'll get a bit of a hissing sound but it goes away within a couple minutes depending on the ambient temperature.
does running intake over a hot running engine not make the (cold air) warmed by the hot engine bay!!
+mikestrong77 He said he wrapped it in thermal fabric and it helped.

No I don't know. Maybe the next time I'm at pick a part I'll see if they have any 89 Cherokee's and check it out.
so you basically can't drive in the rain or any water that will hit the hood?

yes it does . I have driven it in the rain before with no problem
What did you use to do your hood vents ?
If you are referring to the hardware I used, that is 1/2 x 3/4 aluminum angle. The vents them self are from a 86 Chrysler La Baron turbo.
Thanks
Do you think this would work on a 93 zj
what hood vents are those?
Chrysler Le Barron Turbo around 1985 to 88 and the New Yorker Turbo

12:45 Blow By what??
MrKnaberaps a blow by is a device that catches oil that gets spit out the crank case ventilation valve.
Here's my only concern or question isn't the blow by supposed to be filtered before the intake manifold?
hack but ill give credit
What about rain?
It's called water injection lol. I've driven this thing in Rain many times never had a problem.
where is your mass air flow sensor
There is none on a 4.0. It does have a MAP senior, witch is mounted on the throttle body.
This makes it extremely loud inside the cab. Every time you open the throttle it sounds like your registration is going to get sucked through the glove box. Also it looks pretty ghetto.

You still haven't mentioned anything about the heat coming through your hood vents and going into your air intake
I simply ask because I am getting ready to do this project to my Jeep I have a 96 Jeep Cherokee XJ 4.0 with an automatic it is also the rare 2-door
Kelby Braggs
That most likely would only happen at low speeds. Cuz you're getting a cowl induction effect off the windshield
What about water intrusion when it’s raining
When the engine is not running the water is simply going to run through the filter from one side to the other not down the intake.
And when the engine is running I would imagine it does suck a little bit of water I have never had a problem and it is more like steam cleaning the combustion chamber.
What's the part number for the 90 off the throttle body?
