I just purchased NGK Iridiums (ix's) from Advance (as I took the advise from reading the other threads here) and they are gapped to 0.044. Is that cool for my 98 WS6?

I put mine in right out of the box with the gap as set by NGK. They run fine. I think that having the proper heat range plug for the way you drive or how your engine is set up makes more of a performance difference than the plug gap. Remember, as the plug wears the gap will increase. The plug manufacturer's preset gap is usually within "shotgun" range (unchoked, that is).

I believe alot of guys were saying to gap around .45-.50 for stock and mild bolt on cars. FI and Nitrous was tighter gap I think. Cant remember for sure but you should be fine with .44 I would say1999 T/A WS6 Black -------SOLD
