Comments: This was one of my first upgrades because I just had to do something. Probably wasn't the best choice in terms of upgrade choice but it is a good product. Instructions were great. Parts made perfect fit and the chrome tube is very sharp. Has it made a difference in performance? Maybe, maybe not, but it definitely hasn't hurt. I'd do it again.

Price: $245.00
Pros: It's an intake.
Cons: None
Recommended? Yes

Comments: Not sure if it adds a lot to the program but it was on the jeep when I bought it.

Price: $100.00
Pros: Easy installation. Great sound when accelerating.

Recommended? Yes

Comments: Picked it up at Quadratec's annual scratch and dent tent sale! They had three of them, all open box, all missing one or two different parts each.

I did some creative swapping of parts, and bought a complete kit for $100.

Price: $270.00
Recommended? Yes

Comments: The only thing I had to do was drill air sensor hole. It was a bummer at first, but works great now.

Pros: noticable but small power increase , i only had intake and filter not throttle body spacer
Cons: rubbing of heat shield to intake pipe almost ate a line through the pipe
Recommended? Yes

Comments: paid a little over 250 i think. Not really worth it. Id say its a good mod for the 100 - 150 price range otherwise just save your cash. Sounds nicer though.
