Like the listing said. I have a k&n for sale, obviously for the 03/04 cobra. This thing definately makes the blower scream, and gives you the hp it promises. I dont know if it is 30.2 , like it says, but it was a definately noticeable amount. The filter is basically new. I even have the recharge kit, and will clean it and recharge it before it goes out so it will be practically new. Make offers. I decided to go with the JLT CAI instead. This was a good choice though, blower is louder with this over the JLT.
