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 - 6 years ago

Slow speeds as in 4-wheel low drive slow speeds. So it only works as a cold air intake at high speeds

martinbuilt - 6 years ago

Kelby Braggs
That most likely would only happen at low speeds. Cuz you're getting a cowl induction effect off the windshield

Kelby Braggs - 6 years ago

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 - 6 years ago

You still haven't mentioned anything about the heat coming through your hood vents and going into your air intake

martinbuilt - 6 years ago

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.

Kelby Braggs - 6 years ago

Please don't take me as trying to be a smart-ass this is one question that I I am truly asking from one Tinker to another

Chris Garneau - 6 years ago

what hood vents are those?

martinbuilt - 6 years ago

Chrysler Le Barron Turbo around 1985 to 88 and the New Yorker Turbo

how crazy is it to do this with a 2013 mustang. i got a cowl hood

Joe - 7 years ago

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.

Matthew Andrews - 7 years ago

Joe He did something wrong then. Everyone I've talked to saris or makes a slight sound at startup and that's it.

martinbuilt - 7 years ago

Joe

my only seems to be loud when you first start it up at initial cold starts.

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.

Random Acts - 8 years ago

where is your mass air flow sensor

martinbuilt - 8 years ago

There is none on a 4.0. It does have a MAP senior, witch is mounted on the throttle body.

glow stone - 8 years ago

great idea but ive swamped my hood more than once with enuff water to drown that filter i think.

martinbuilt - 8 years ago

Yeah it's not for everyone

hyper1313 - 8 years ago

hack but ill give credit

splitsonface - 8 years ago

What are the dimensions of the blue elbow at the throttle body?

never seen anyone do a CAI in the cowl before. Very nice.

logan smith - 8 years ago

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

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.

yogitunes - 8 years ago

nice job......brilliant and handsome.....from one martin to another.........nice beard too........keep the ideas and videos coming......

Jeremy Edlind - 8 years ago

Where and what brand do you recommend concerning the heat wrap?

martinbuilt - 8 years ago

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.

OJ Sutton - 8 years ago

+martinbuilt On the 89 that side of the cowl does not open do you know if there is anything under it or can I just cut through it

jeremy edlind - 8 years ago

+martinbuilt thanks buddy!!!

martinbuilt - 8 years ago

I believe I used thermal wrap that I purchased at AutoZone

Caleb Gallas - 8 years ago

Can you get a list of the sizes of emt and 90 degree elbows please? Great video!

martinbuilt - 8 years ago

+Caleb Gallas The 90's are 3.5 inch inside dia. I believe the emt is 3 inch even though it measures more like 3 3/8 inside dia.

Nicholas Koenig - 8 years ago

What size is the end of the 90* coupler that connects to the throttle body?

TruthWarrior - 8 years ago

What are your thoughts on a throttle body spacer, like something from Rough Country? It gets high reviews. Have you ever run one?

martinbuilt - 8 years ago

+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.

Karo Staro - 8 years ago

so you basically can't drive in the rain or any water that will hit the hood?

martinbuilt - 8 years ago

+Karo Staro
no you don't understand the filter is horizontal I mean the water runs through it, through the top through the bottom of the filter it does not run into the filter and then down the intake tube it cannot do that.

Karo Staro - 8 years ago

idk point is to keep the air filter dry at all times. if it runs through it it'll run inside

martinbuilt - 8 years ago

+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.

martinbuilt - 8 years ago

Bryan Webster - 8 years ago

+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.

martinbuilt - 8 years ago

I have driven in the rain many times and never had any problem whatsoever. the Jeep has been parked out in the rain before starts right up.

mikestrong77 - 9 years ago

does running intake over a hot running engine not make the (cold air) warmed by the hot engine bay!!

No Need To Know - 8 years ago

+mikestrong77 He said he wrapped it in thermal fabric and it helped.

uvha X - 9 years ago

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.

martinbuilt - 9 years ago

+uvha X I just think the Spectre has a small filter. but I like the idea or design.

Jack shirley - 9 years ago

wow great video thanks for takeing the time
Parts List please

Paul Janda - 9 years ago

That is a great solution. Might be the coolest CAI I've seen on an XJ.

martinbuilt - 9 years ago

Thank you, it has been workin a great for me.

Stray D.O.G freedom - 9 years ago

Very cool. What'd you use for your hood lift arms?

martinbuilt - 9 years ago

Lift Hood. I believe they were 80 or 90.00

xXxLokiDriftxXx - 9 years ago

Do you think this would work on a 93 zj

Isabeau Touchard - 10 years ago

what about water? rain car wash and other?? it looks like it will suck it in.

martinbuilt - 7 years ago

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

MNT HUNTING - 10 years ago

Cool idea now how well does it perform compared to a normal cold air intake?
I have a 96 and would like to trick it out.
Cheers...

martinbuilt - 10 years ago

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

MrKnaberaps - 10 years ago

12:45 Blow By what??

Lance Hamilton - 9 years ago

+MrKnaberaps a blow by is a device that catches oil that gets spit out the crank case ventilation valve.

MrKnaberaps - 10 years ago

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 :)

What did you use to do your hood vents ?

Norman Murray - 10 years ago

Thanks

martinbuilt - 10 years ago

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.

Gene Westburg - 10 years ago

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

martinbuilt - 10 years ago

Gene,
Yes the tubing is all EMT. the 90's I got off of ebay. I think I got the heat wrap from ebay as well but it could have been from Summit.

brian k - 10 years ago

ShawnMrFixitlee - 10 years ago

A bit of a pain to clean the air filter .. But I like the Idea of true cold air !!

Gordon Fava - 10 years ago

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.

martinbuilt - 10 years ago

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.

Biking&Jeeping - 10 years ago

Have any of the xj owners have or had a problem with the dash lights not working. I have replaced the headlight switch but the fuse is still blowing.

01Durango5.9R/T - 10 years ago

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.
