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

Noticeable increase in power, acceleration and MPGs. Installation was fairly easy but for some reason I had extra screw and nuts(?). I used You Tube and written instructions provided. There is a loud drone sound at mid range but quiet when running low RPMs. Best music is climbing steep grade or passing on freeway. I highly recommend.
