I hate to even ask this, because I know it has been beat to death somewhere. I cant seem to find any recent threads, and all the numbers I can find are just confusing the Autozone peeps. What are you guys running for plugs on your 1JZs? Are 3330's still a good bet? I plan to be BPU, so I figured one heat range colder. Advice?

 

I am running the cheapest NGK. Like $1.99 a piece. Gapped at .025. I think they are 4445 ones.

 

Thanks pal.

 

NGK 7092 aka bkr6egp.
Platinum 6 heat range, leave as is gapped out of the box if your ignition system is in good condition. Shouldn't ever have to go under .032 on stock twins, ever, unless something is wrong. These plugs idle perfect for a bpu tt car. Cheap at autozone too. They last longer than the coppers.

 

What would you suggest on a 1uz?
