I wonder what the maintenance schedule for the OEM plugs are, it would suck for the dealer to change them and notice they are the wrong ones |
I believe the plugs are 40k items, and the S55 plugs are two steps colder I believe. Cold start this morning was fine and I don't think it will effect any scheduled maintenance, but since the engine is running hotter with a tune, I plan on changing my plugs every 25K. HTH.
Talk to Nick about the plugs, he should be able to inform you better then me!
