i hear a lot of those spark plug non foulers, used to get the downstream oxygen sensor further away from the exhaust stream, when removed the cat, and keeping the mil light off, anyone having experience with this ?

I have never used those myself, but I have read that they do work for some people.

They work great, and are very easy to install. Period.
