K&N Intake

How many of you guys are running the K&N intake on your 4.0 jeeps?

This is the one I am referencing..

If you don't need the real estate (e.g. for a York compressor) gained from removing the stock airbox, I wouldn't bother with the K&N.

I've got the AFE and it didn't make any noticable power difference. If you don't mind cleaning your filters it can save you a few bucks over replacing them all the time.

Not that I can tell. I put on some Gibson exaust at the same time. Don't think that really made much difference either, at least not enough to "feel". If you put it on a dyno I bet you might see a couple ponies with those mods together. But from what I can tell, it just sounds a little deeper for the most part. If you want more power or better milage, proper gearing is the way to go. Stay away from throttle body spacers and chips too....they are a waste of money on the 4.0 liter.
