spark plugs

a friend of mine installed some NGK 6510's in his car after speaking with his tuner. after second guessing him and asking way too many other people, he is nervous that they are the wrong plugs. does anyone here know if they are correct?

Yeah I saw that. I was just hoping he wouldnt have to change them again. His tuner Must not know what he was talkung about or gotten confused.
thanks for the reply, I told him to change to whatever came on the hhp website. im sure that's what he will end up doing. I just hope they wont mess up his motor before he changes them.
