DO NOT PUT THOSE PLUGS IN YOUR V10!!! they are known to cause MAJOR problems. i had a v10 come into the shop i was working at. the owner was running them. they came apart in his motor the tips are way brittle and they fowl easy. screwed the engine. funny thing is he got them put in at the DEALER.
i highly recomend running the irridium plugs. found below.
i hope i dont get into trouble for linking you there. the above plugs are what they run in the v10 vipers.
