Poor Instructions, waste of money & time.
The kit for my vehicle did not fit well at all. I have been in the automotive parts & service industry my whole life. I have never seen worse instructions. They state several times to use bolts included in the hardware, no indication which bolt size or type. My emission hose in the kit is about three times the diameter of the one on my vehicle. Still trying to resolve that. The instructions didn't even include my model and which air intake it should use, they included a choice of two.
This is the forth vehicle I have installed the K&N 63 Air Charger in. I love the increased HP and the growl when you put your foot into it. There is a definite power difference in the vehicles. Installation is easy enough if you have basic tool/automotive knowledge. I will install one in my next vehicle also.
