This is the best thing I have had in awhile and makes a huge difference.

Expectid to be able to take the old air system out and just hook up the new k&n system and done. Sadly it was not that easy. The holes for the grommets were to small making the hole in the grommet to small for the air sensor. I had to open up the hole with a die grinder to get it to work. Also there id no hole for the air injection tube. Lucky i already had a 1-1/4 hole saw or i would of had to go buy that too. Sill love the product and the brand

I am very pleased with the perfprmance of the K&N 63 Air Charger. I bought this due to previous experience with K&N. Installation was a bit of a problem due to some incomplete instructions. All in all, very pleased with it & will gladly purchase one again if needed.
