does anyone know the specs on how much to torque the spark plugs and the sparkplug gaps???? thanks
what kind of performance difference's are noticed when you do iridium and platinum plugs. and if you run these how often are you changing them out? what's the interval change times for these?if you buy iridium plugs..you dont hae to worry about the gap...same with platinum tip plugs...and you get better performance

This is somewhat normal on plugs with a buch of miles on them.. the gap increases as they get hot.., after so many thousands of times expanding and contracting, they wind up loosing thier original gap and expand.. thats why people feel a difference when replacing old plugs.. its mainly due to improving the gap.I know that this thread is a couple of months old, but I just changed my plugs today and I checked the old (factory plugs) just out of curiousity, and they were gapped to .045 or so. I gapped the new ones to about .035 (the owner's manual calls for .032 or something). Anyone else's factory plugs seem to have an overly large gap? I just wonder if this is a more ideal setting.
