    It says they are:

    •Inspect for aftermarket components, such as an exhaust, ignition, high performance air filter (K and N style), or air intake system. Take photos and document accordingly if anything is found.

    Not a mechanic or a tuner, but, I am in agreement with the line of thought that an intake, exhaust, and a tune to compensate for those things (reasonable timing advance, MAF/IAT tables, etc.) is not gonna blow a hole in a piston.

    On that note, what kind of "Radical Tune" (with regards to timing) would it take to do this?

    An extremely lean condition can cause a piston to melt, and timing that is too far advanced can cause a piston to chip.

    I just found out the cylinder 1,3,5,7 is misfiring badly and o2 sensor bank 1 is causing check engine light to come on, would that make my g8 pistons bad
