I did the MSD coil conversion for 2.4's with Taylor thundervolt wires and ngk tr6's. The car runs 10 x's better, I think my old coils were dying.I noticed my gas mileage losing a mile or two per gallon. I don't know if it's because it runs better and I been having my foot in the throttle. Or is it because I am not running platinum plugs. What plugs did everyone use with their conversion? I just have basic upgrades header, exhaust, 59mm tb, intake
Wrench would it hurt anything if I put NGK plat's in? Will they make any difference or is it a mind thing?
