I use NGK V-groove TR6's I believe. Or maybe its the TR55, I cant remember at the moment. I remember one is for nitrous applications and the other is better for NA.
They are so cheap I swap them out every other oil change. The car loves'em.

No, you won't notice any difference whatsoever. The idea is to point the spark toward the intake charge to ignite the fuel/air mixture quicker rather than hiding the spark behind the electrode possibly delaying any ignition nanoseconds later. It's really just the principle of making more sense for the physical rotational position of the plugs.....just another fun thing to do in your spare time where it's free and doesn't hurt!

I swap them and index the new ones. The starter should last forever as it never cranks. Just a touch! Tr-6's for F/I right out of the box. I just check to make sure their gapped the same. tr-06 comes @.039 tr-55 @ .059 if I remember right
