well my truck wouldnt start and the plugs were fouled up pretty bad and i broke one when i took em out(im a master mechanic
)lol. so i ended up buyin some new ones, went with bosch platinum as ive heard good things about them and im pretty impressed. my truck fired right up and the silver bullet seems to have a little bit more pep. been running better too. we'll see how they last.
btw, i was gonna get the platinum 2's but the guy at autozone said they didnt have the 2's or 4's for my truck...i find that hard to believe but whatever...i wasnt to worried about it.
