A little exspensive but worth it exspecialy when added to volant cold air intake. Installation is s breeze.

Easy to install takes about as long as it takes to put in a air filter element. Its almost too easy. My 2006 Gmc Envoy 5.3 v-8 picked up about 1.4 mpg thanks to this spacer. It made the check engine light come a couple of times but it finally got use to it and it no longer does.Also seems like it is more responsive. Good product two thumbs up Thanks Rich

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
