any way i took a piece of 3" stainless exhaust pipe in a 12" length cut the needed holes for the hses from the airbox i brazzed on the needed fittings and went out and got the biggest K&N filter they had(6X9K&N w/3" mouth) slapped it all together and tossed that crappy old restrictive airbox and havent had a regret

Comments: Finished my cold air intake with heat shield and installed it. The difference..... WOW!!!! It has a lot more throttle response over the whole power band. It will now break the tires loose from a dead stop. The exhaust note is deeper and more aggressive sounding. Oh and there is a nice whir sound every time I give it some gas! Also I gained about 3.5 mpg by doing this. My average before was 16.7 and on the same trip with the same weight and amount of fuel and cruising at the same speed I was averaging 20.2 mpg. Not bad for a v8 with the np249.

Comments: i made my own intake using pvc piping. With some cutting and painting with the steady hand, the results are amazing. My engine can finally breathe in the high rpms.

Comments: I made a cheap and easy cold air box by cutting a sun deflector shade into shape as a heat shield and also wrapping part of it on the intake tube. I then cut out part of the air box to give it some more flow. Oh ya, and a drop-in K&N. Sounds great and seems to help quite a bit!

Comments: This a copy of the AEM/K&N intake. I have access to a mandrel bender. I used 3.5" tube for the charge pipe. Fabricated some sheet metal as a heat shield. Also covered up the hole below the air box to avoid water intake.

Comments: Yes, eBay. Haters go away. Money is tight. Got a simple long tube intake, with a great filter. Eventually will get an AEM Brute Force intake. But for now, this works wonderfully.

Comments: Modified the stock air box by jigging out the front and side of the box so it gets better air flow and sounds better. Really loud! But Also free and you can't beat that.

HomeMade Custom coldair intake
Pros: Thermotec products have so far worked as advertised; Better Running Jeep at all RPMs
Cons: Intake Manifold is a b!tch to wrap completely; Entire Setup is a bit of a beta test -- see how it holds up
Recommended? Yes

Comments: I have tried a variety of intakes - stock, w/KN panel, Cone with metal tube, back to stock and paper. The one thing that alway bugged me about any of the so-called cold air setups for Wranglers was the heat-soak you'd still be facing having the intake manifold right above the exhaust manifold. Touch the intake manifold some time after you've been driving for a while -- it'll be burning hot.

I was going to leave everything stock -- airbox and paper filter -- and just wrap the intake manfold in some thermotec tape. But I said "what if I took this cold air business a little further." And of course a project ensued:

With the apparent intake temperature drop, low end is nice now. You move out a lot quicker. At highway speeds you do probably get a slight positive pressure, too -- like 1/10th of 1% lol I don't have the plastic rectangular headlight pieces in place currently and I have both my front signal lights out. I put all that stuff in and I am going to have to attach something to the grill that flows incoming air past the grill to the left side where the intake opening is. This should cut out any heat perhaps given off by the radiator as well.

As for water intake, not much chance -- its not one of these Honda cone-filter under the bumper deals. I need to go through water I'll just unscrew the hose from the metal behind the grill and keep it high in the engine bay.

But point of all this is, yeah you can get some good results out of the 4Banger using the heat wrap products by Thermotec and then do a little filter shopping and metal hole boring.

Comments: in response to the snorkle comment it is a great mod unless i plan on doing high water crossings which i try to avoid cause a snorkle is usless if your not water proofed which in the cases of most snorkles out there they arent water prooed which can lead to a world of fun in electrical demons, milkshake fluids and so on

and mine isnt very loud at all i get a slight whistle from the vaccum lines cause its more open now but aside from that not realy noticeable
