Installed a set of NGK Ruthenium spark plugs gapped at .028. Expy drives like it did after I had it first tuned (big difference). Only 2 of the old plugs were white at the electrodes. OD 47k.

According to the description on the RockAuto site, they come pregapped at .032? If tuned, or regularly running hard, .028 is the better gap. You mention that yet the description says .032?

@LokiWolf Thanks for recommending these plugs in the first place! So, rockauto says gapped at .032 when I measured them they were all at .030 or .029. I gapped them to .028.
