this is awesome, yea the plugs I bought are pre-gapped, so it should be a done deal. I guess I'll just spend a few hours figuring out the easiest way to get them in, I have a feeling that I will have trouble with 3 of them, since there are a lot of parts in the way. straight shot to most, but not all. btw, your car looks awesome! thanks

I just bought a set of NGK platinum for my 2000 GS400, and about to install. I then called the dealer to verify, and they said they use Nipoon Denzos. Is there a downside to using NGK platinums? will I cause damage to my engine? thanks. cous 2000 GS400
