    3V spark plug PICS

    Any idea what caused the bent rod? I thought the Saleen was very conservative on the tune and psi on these stock engines. I mean that you really don't here of a lot of engine failures unless someone is really pushing the limits of the stock internals or running a crap tune on an FI application.

    3V Spark plug change hell
