Post Cold Air Intake...?

How 'bout some opinions from those who are running CAI on their TJ.

I've been looking into K&N, AirRaid, etc. I haven't been able to come up with any dependable info/data/testimony to help me decide if it's worth it, and if so, which setup is the best bang for the buck. I have a buddy who is a DC master tech who's opinion was basically that it *might* make the slightest difference and I'll likely never notice any benefits. But, he's not a Jeeper, so I'm asking you guys instead.

I guess the first question is: Should I even waste the money? I mean, will I ever REALLY know and appreciate the money spent? Or is it just a mod for the hell of it kinda thing?

Thanks.

And yes, I've read quite a bit of data on them and all the *claims*.

Yeah, that's what I was thinking. I was sort of hoping to hear some positive reports b/c I sure wouldn't mind gaining some HP and mpg as claimed. Just seems questionable. With a SMALL budget for mods, I don't want to waste $300 when I could get other goodies.

I just put the AEM on my 04 TJ. I'm way under geared and over tired for now, and have totally lost 5th with 33's and 3.07 gears. I've noticed at night when the temp drops down, I can maintain 5th gear, after adding the intake, but with no acceleration. So it' did make some difference. There's also comes with a throttle body spacer. That does increase manifold vaccume at lower RPM's, which could be responsable for what I've noticed. I also watched the air intake temp on my SnapOn MT2500 scanner for a few days waiting on it to come in. Before temp in town with AC on was from 145 to 155. It now stays below 115. I hope to see milage increase from the cooler air, but can't dream about in power till my gears and master install kits come in.

Look on ebay first, I got a good new performance air intake off of ebay for $50. I notice hp and fuel gains, and it improves the engine sound.

The only reason I see to use a "CIA" is if you get tube fenders and can't use the stock air box any more.

Not worth the money IMO. I have the Airaid CAI and T-body spacer. Gave me a slight increase in power but not much and increased my MPG by 1 or 2. I have been thinking about reinstalling the stock box.

My concern with CAI's is if you go into a lot of mud, a cold air intake is going to provide almost no protection from water ingestion whereas the stock box provides at least a little protection... In my opinion, if you are gonna drop money on any kind of intake, I would get a Snorkel.

Thats kinda what im holding out for, it basically acts as a CAI anyway, and puddles can still get down and dirty in the deep puddles.

IMO not for what I paid for it, and as was said by someone else I have experienced the downfall of a CAI in water. Best way to cure the milage issue is figure out a way to install a diesel in them without breaking the bank.

Do you street race or run the quarter-mile at the dragstrips? If not, you don't need nor will you benefit from a CAI.

Obviously there are many different opinions on this subject. You're gonna have to make this decision for yourself.

I suspect that eBay CAI product increased the engine's placebo power effect by at least 6.2%.

My CAI came off ebay as well. It cost me $40 - $50. Sounds beefy, and I can feel an increase in mainly midrange power.

They're pretty much snake oil. Anything you think you feel is just that - thinking you feel a difference. Personally I wouldn't waste any money on one myself. I have one but the only reason it's there is due to the fact that I had to remove my factory air box for my tube fenders.

if you get rid of the stock airbox then you have to relocate that rubber line coming off the airbox...

If you wheel where it gets dusty, and most of us do, I strongly recommend you put some kind of a prefilter on your K&N. Something like an Outerwears so long as it fits snugly over so dust can't get around the side of it. K&N air filters are notorious for how much dust and silica they pass.

jerry you stole what I was going to say about the outerwears and dust. oh well. something that you didn't mention is that they block out water and mud as well which is a great investment around $27 especially if you live in a wet environment like us fish here in oregon. I didn't really notice any difference in HP when I added the intake and TBS but I did notice throttle response time improved quite a bit (to me its worth it) I also put on the 4.0L TB so maybe that had something to do with it. as far as HP goes did nothing really.

Thanks for all the reponses. Looks like my money may be better spent on the usual suspects. Tires, wheels, HiLift, Lights, and the road goes on forever....
