Pros: Instant Improvement
Cons: High $$$
Recommended? Yes

Comments: Simple Install Just bolt on ... easy clean-up with warm water. If you remove the 'side riser' on the side of the factory airbox it wakes up even more... And has an awesome sound. Saves gas...

Pros: Easy to instal, Cheap upgrade, Washable
Cons: None
Recommended? Yes

Comments: I like the K&N filter, Yes it is more expensive than your average air filter you'll pick up at your local NAPA or Jiffy Lube when you get your oil changed but its washable! It will long out last a few of our Jeeps. So.. I bought one. The Jeep seems to like it, It gets up to speed easier and you can simply hear that it is breathing better when you step on the gas. Id recomend one to anyone.

Price: $15.00
Pros: Better airflow equals more power, slightly better fuel economy if light on gas pedal.
Cons: None. K&N is a proven brand and way to mod a car/SUV.
Recommended? Yes

Comments: My Jeep came with the K&N filter already. It doesn't have the full CAI set-up yet but that is something I'll install in due time. The K&N air filter is much better for airflow and power over the stock restrictive filter that looks like paper with honeycombs over it. I've noticed a nice difference with K&N products in the past on former vehicles. On my other Jeep Grand Cherokee it had a stock filter and comparing it to my new WK, there's a nice growl and slightly more power with it.

Pros: Everything
Cons: None
Recommended? Yes

Comments: Although I have the stock replacement filter and not the full cold air intake, it's still a great investment. Engine breaths easier, don't have to change it till a million miles which saves you money in the ling run as well. All around excellent product.

Price: $40.00
Pros: I'm getting ~1mpg better mileage at best.
Cons: Still debating rather it is worth it or not.
Recommended? No

Comments: K&N is ok, I think MPG wise it may be a touch better than a paper filter. However once you add in the cost of a recharge kit at $10 per year + $40 for the filter you are invested in the same amount to put a paper filter on for ~4 or so years.

Some people say it lets more fine particulate into the engine and that's probably accurate. I don't regret purchasing it, however if I had it to do over again I probably wouldn't.
