Hey guys...
I made the mistake of asking a question way down in a thread on coil failures , so I figured if I wanted an answer I'd better start here!
I just wondered about my Ford esp extended warranty.Meaning , If a person puts performance exhaust on his Ls , will it cause warranty issues if and WHEN said person experiences driveline failure.The old story is that "they" will do anything to get out of warranty work , IF they can fault the car owner. IE:aftermarket upgrades.
Thanx in advance,
Ken.

No, not unless the part is damged do to the aftermarket use. That is in the waranty guide.

I even cheese graded my Intake box before I found Ls Koncept's, they didnt care.
