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

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
