| from a set #6 NGK platinums @ .035 a couple of weeks ago. I was suprised how much smoother/responsive the car seems at low RPMs and 16psi, It seems to have picked up power as well(unscientific tho). I need to get some race fuel and try a couple of 20+ psi runs soon. Stay away from the Denso Iridiums, people have had issues in the past with missing-poor performace.
