Thanks guys.

What I would personally do is clean it up and make sure that there are NO holes in it (from being stepped on). Then separate any crushed fins (no need to go crazy, just open them a bit).

If there are no holes in, id let it soak in hot water and dawny for about an hour or so and then rinse it with a hose from the inside outwards, let it dry, oil it up (lightly) and pop it back in.

If its ripped however, just junk it and replace it...although they are $50-60.

Just as a reference point, I have had the same K&N that ive been carrying from car to car for about 5 years now. I clean it every 6 months and its been holding up fantastic. As a matter fact, I just put it on the new-to-me 4.0 TJ last night after washing it!

Yeah, I disagree with facts all the time too. So what if the air mixes with the fuel well AFTER it passes the throttle body spacer? My mom says it looks cool! ...and moms know everything about automobiles. She even pumped her own gas once!

The fins are all crushed and its semi flattened instead of round like it supposed to be. I can get a new one for around 40 bucks or so.

$40 is cheap in the long run. I wouldn't chance it and just buy the replacement.

OK, so I've got a K&N from the previous owner, not CARB certified so it won't pass smog. I don't mind going back to the stock air box but I'm not having much luck finding one. Any suggestions?

IIRC all K&N CAI are CARB before they release them. Whats the problem? The filter or the whole thing? If its the filter go buy a cheap ricer paper one for the test. That or a buddy with a stock set-up and throw it on for the test and then switch back. Many ways around that problem, Good luck

I got a question for you guy's


How much cfm does a 4.0 need?

I'd like to use a donaldson pre cleaner on a cowl snorkel setup, but need to know which size to spec out based on how much cfm the intake will need to flow.

4.0L sucks about 385 cfm at WOT at redline. the stock throttle body flows about 450 cfm.

those that always reference the JP Magazine for Intake Shootouts should read this:

Quote:
Sometime between the last test and this one, we had formed a working theory that it wasn't so much the air filter as the air tube that makes the power in these kits. With most, if not all, aftermarket air intakes, the air filter itself can flow more air than the Jeep can use. Sure, there are varying degrees of restriction from one filter to the next, but on a stock 4.0l engine we just aren't convinced that a significant result will be seen at the wheels from the air filter alone.

i actually had a guy tell me he added 2.5 mpg and a few HP by adding a CAI and throttle body. he refused to listen to what i said.. he then said above 10,000ft is when he could really tell the difference.. i then asked him if he noticed it going down the moutain and he said yup!

So i should sell my Airaid cold air intake, and get a stock air intake and use the money towards other gear like new tires. Sorry i know this is kinda old but if anyone wants to answer, thats cool with me

Good idea. If you want a real cold air intake call the guy at Skinnypetal.com and ask him if he has anymore MCAI's available. I have the older version of this on mine and it works great. I can actually feel the power increase and it has the added advantage of filtering the cab air when you have the top on and it dual filters the intake air. It also gets the air inlet up a little higher.

This is the intake:
http://skinnypedal.net/store/index.p...roducts_id=108



He doesn't show the cowl scoop and filter, but call and ask.

The cowl scoop and filter was originally developed to just filter the interior/cab air so dust can be eliminated entering the A/C system and plugging the evaporator and heater core and had the added benefit of letting you breath better on dusty trails. Skinnypetal bought the idea from that guy but it could be it is no longer available. It used the stock Jeep air filter in the cowl vent.

Here is the cowl scoop and filter on mine.



I have the older intake design which uses a GM paper filter. The skinnypetal uses a conical filter.

I suggest you call or email them and ask.
