My 05 Chevy Colorado was at the dealer for a check engine code that they said called for 2 new catalytic convertors at a cost of $1200.00. I got a bottle of this to try instead(I did NOT approve new convertors), & after using it like instructed, the check engine light went out & hasn't come back on. So it could be a fluke, but it worked for me !

Fits and works great. Edges provided extra grip and plenty of protection, and the squared off edges give a unique look not offered by other case. The clear back is fairly scratch resistant as well.
