The plugs you got are NOT the ones Mopar is reccommending. They actually say "PLZ...", those are the premium lazer platinum plugs. I know, I know, everyones says plat plugs aren't good for our turbos, but they are wrong. ptcruise just had this dicussion and someone posted info on temp factors (the main reason plat plugs are poo-pooed) and they are well within the standars for our cars! I suggest iridiums. And your gap may not right be proper either.

Topless - When I called the Mopar tech line about the plugs, they said the stock nbr was 4306 which matched the pro - V plugs LZ. When I mentioned the PLZ platiniums he said that must have been a typo. @#@#@# who the heck is right? I talked with TThrift and he said to use the LZ's. Guess I'll live with what I have for now. Only starts hard on first start in the morning. The rest of the time its starts right up. Thanks people for all the advice. I appreciate it.

It may be just a typo, but it seems they haven't corrected it. Everyone who has ordered 05 S1 has the same instruction sheet with "PLZ..." reference. Nobody is using plat plugs as far as I know, I was just putting it out there that the temperature problems associated with them are not really as relevent as you might think. The melting point of plat is just above 2400 degrees and the GT engine burns right around 1760. Iridium is way up there at 4400 or so. So the iridiums are definitly the best way to go.
