I know this has been said, but I'll throw in my $0.02
Bosch Platinum + plugs WILL cause engine problems in any car not made in Wolfsburg. I dunno why, but every time we put a set of them in at work there is some sort of engine problem. Problems range from loss of power, to rough idle, to major misfire and check engine lamp to come on. SO...don't use them. Get some cheap NGK copper plugs. They're like $2.00 each and you can easily change them, so platinum plugs are really unnecessary.
