I really would of taken that can off, i know it didn't cause it, you know it didn't cause it even your service writer knows it didn't cause it. But i wouldn't be even the least bit shocked if that engineer voids it's coverage the second he sees it attached to the motor.
Just a quick question but i wonder how many people even realize that this current government EPA has bills out right now looking to not only make it illegal to own a street legal track car, but to make things like custom tunes, superchargers, turbos anything that modifies a stock engine essentially illegal. I'm just amazed on a site like this i have not seen a single thread on this unless i missed it.
