I am thinking a buying a Greddy Airinx intake, but I was curious if anyone has had any problems with it. As far as performance gains are there any? Should I install one would it kick a check engine light or cause any other problems? Thanks

I had one, didnt notice any different. I didnt have any EM at the time either. It just made noise.

Sold it to a friend with a link, and he said he was getting all kinds of crazy knock, and running lean with it.

no cels either.
