I changed from the Bosch Platinum 4s to Autolite Platinum 2 at .052 gap like the computer showed was oe plugs. My son swears it slowed the car down. I just dont like the design and no gap feature of the 4s. They also look like they are 1/2" closer to the pistons by the long thread design! Ive always ran normal desined plugs in my race cars and stuff. We are running just the usual bolt ons and gear. The 96 just has no power
