Changing my floormats gave me 15hp apiece!

Actually, I think plugs are the thing that will never actually give you hp, but you need to do in order to take advantage of your other mods.

When I put the NOS in, I was thinking about those Bosch +4 plugs (if they even make a Supra fitment). Anyone know about them? High grade platinum, with 4 tips, so the spark is finding the coolest path possible.
Just get the NGK 3330 plugs.

From my experience, Bosch Platium +4's are horrible in japanese cars.
