Ok, so I built my "homebrew" cold air kit the other day, and I am curious to see if it's "up to snuff" with the aftermarket/ other home built kits. If any of you have aftermarket or home built cold air kits please post pics and a general list of materials used. I'll post some of mine tomorrow as it's dark out and the squito's are out in force at the moment.

 

if you search homemade cold air intake on here it will come up with alot of threads

just a bit of advice make a shield of some type to help block water from your intake so you dont hydro lock like i did.

 

I was going to suggest the same but not so much as a water block as a heat block. A "cold air intake" isnt worth it if you are sucking in the hot air from under the hood. Block off the rest of the engine and pull fresh air from behind the grille.

 

On that note, there are three holes directally underneath your airbox that go right into your fender well, one of them is pretty big and the others are a little smaller but what i did is took some window screen and put a couple layers over it. It might be a little overkill but i didnt want any mud or water shootin up into your cone especially if its one of them premade expencive kits.

 

I hacked the crap outta my air box to get the massive K&N cone filter to fit. I took some thin metal and pop rivits and did a FULL heat shield. Not just a baffle like most kits. I'm gonna go to the jy soon and get another box I can swap out for when I do mudding and wheeling with anywater. Right now it's my DD so no water, no mud (no where where it's legal anymore) just fire roads.

 

True cold air intakes on 4WD vehicles sounds retarded to me. To really pull in cold air the filter must be drawing air from outside the engine bay and most kits simply hang the cone right behind the headlight or have it pull air from beneath the engine compartment. Either way even hitting a deep puddle at 20mph you stand a good chance of sucking tons of water through your intake.

Cherokees are not sports cars anyways my engine is totally stock and im happy with the amount of power it makes. If you do run a CAI be sure to switch back to stock before you go wheeling.

 

that was the exact mistake i made except i was doin like 10mph, i think it was like a liter of water that poured out of my spark plugs, it was bad
