groundhounds cai concept

I was at that site you sent, That would seem fine on the street(no dust)
but out here in the desert with the intense dust, but then most of the dust
is kicked up behind the vehicle on the trails, I think it's worth the try.
I'm retired, so I got lots of time for this sort of thing, goofey or not.

I can't help it but, when I see words like "K&N", "RP", "Amsoil" and "Fram", I just have to say to myself that these are free thinking consumers and they are entitled to their beliefs. I hope that they respect mine.

I bought the edge kit for the 4.0 (back when it was still close to a grand, but I was young, and didn't know how to work on cars so it was good starter). This was on my 01 DD xj, it comes with an AEM CAI, 62 mm throttle body, and a programer. I didn't get a chance to test the products individually however there was a considerable seat of the pance feel in power and highway driving was considerably easier. However, I've learned that MPG improvement that the manufacturers claim are bold face lies as the whole kit was advertised to give you another 2+ MPG. The best I've ever done with stock tires on it was 24 mpg which is good for the XJ but that was fueling up, getting right on the highway for a straight 320 miles. But around town there was no difference mileage. I put that on about 4 yrs and about 50,000 miles ago and haven't cleaned the filter yet but have never off roaded it.

I did replace the stock paper filter in my 98 v6 s10 with a K&N, again a very very slight seat of the pance feel but no increase in MPG. And the oil absolutely played havoc with the air system as these trucks have a Mass airflow sensor that got clogged up and caused a CEL light. When I replaced the engine (knew a little more about working on cars at this point ) I cleaned the sensor and went back to a paper filter.

I'll maybe never buy another CIA kit again cause like every one else alludes to they just aren't worth the money. I've heard limited success with people making their own for less than 45$ so that may be the way to go, if I ever manage to get my wrangler back in one piece that is .

Just thought I'd chime in on an old but great thread.

That cai issue is behind me now. Sat. I put the old stock filter unit back on did a lot of around town and
local freeway driving. Did not notice any diference what so ever. And that little horn on the stock unit
should draw in less dust out on the trails. Moving on.....

What did you do with the CAI tubing and such? Can I buy it off you? I'm thinking about trying my own cowl-based CAI (partially just to get rid of the airbox from under the hood), and it'd be nice to have some decent starting materials.

Yeah, I still got the so called cai, I was asked if I want to sell it, If he dosn't want it, I'll get back to you.

Interesting thread. It seems that Bigbob is the only one here who might have a setup worthwhile (assuming he didn't spend much money since it's largely homemade). I'm certainly glad I didn't just "assume" the K&N FIPK claim of 12 HP was true. I just bought my 05 Unlimited and the first thing I noticed was "that's a small throttle body ....I doubt an FIPK setup would help HP much". Now from what I'm reading it looks like it's all big enough and that the engine just can't make much use of anymore air. I never realized the K&N's are so poor at filtering ...makes me a little nervous about the fenderwell setup I have on my 450+ RWHP LT1 Z28 ....but at least it's in the fenderwell and covered up fairly well.

Bigbob ...you need to post some pics of your setup please. I might be willing to try yours if it could be fabbed up for a reasonable amount. I figured a cam swap would be the biggest power gain on these (of course that means giving up some of that wonderful off idle torque). I'd like a little more ....like 210 HP. The torque is fine I'd just like a little more at the top (without giving up the torque. Since FIPK / CAI seem to be controversial at best ....ummm, what about a Hypertech or something? Let me guess ....for it to be worthwhile you have to switch to an aggressive enough program that premium fuel is needed, otherwise you incur detonation....correct? Sheesh, I'd love to get some easy/cheap/free HP ..but it doesn't look likely with the 4.0 from what I've read so far (downside of a relatively low power engine from the factory).

Not homemade, but also not on the market yet. There are many of these around. Being patents are pending on it I can't post pictures. I did modify mine quite a bit from the stock design. My modifications were to make the filters easier to service and had nothing to do with performance.

As far as easy to fab one of these up yourself goes, duck soup.

Well after I was at a huge outdoor local car show near here last weekend, and viewed every air cleaner I saw. So many with a large conical shaped filter as the Banks, and most not in a housing as mine, but just there on the end of a fat air duct, I went home and enlarged the opening on the Banks from it's 4"x 6" to twice that.
I'm very low tech, But there sure is a faster response at the tap on the gas. This Jeep is new to me, but I have
not had as much fun with a vehical since my old VW bug's. coldbeer52.

Advance your aftermarket cam 4*...that will give you more torque down low at the small expense of top end. I lost about 300rpm off my redline which really isn't a big deal because my Jeep hardly ever operates at or near redline.

I dont have a CAI on my jeep, but I do on my gas chevy truck and my diesel duramax and they make a world of difference. I wouldnt ever put one on my jeep because it sees alot of water and mud, it is stupid for a jeep unless you stay on the roads. Solid product just not made for my jeep!

If you had a CAI you most likely wouldnt be hitting up mud like that if you were smart?

Yes, because you could totally stop on a trail and reinstall your old one to do the water crossing or unexpected mud hole, then go back to the CAI.

Oh wait, here in the Pineys we don't have the luxury of scheduling our mud holes on the trail.

mud? never been a problem for me. i'v been in some deep sloppy stuff . so much so that mud clogged the throttle body spring and it was stuck open. that just happens to be the only picture i have from under the hood



the filter stays clean. flows much better then stock and i don't go past mid grill at the most in water. never going back to the stock junk
