7 trailing 9 leading I belive.

I would recomment that you run 9's all round.

Unless you are modded, you dont need to run 9s, itll just foul up faster.
Also, I believe it's 7 for the leading (platinum) and 9 for the trailing.

I'd run 9's all around with your mods.

Im like 99% sure its 7 leading and 9 trailing...But I may be wrong.

But I would also recommend 9's for all. You may have to replace them more often, but it will run better overall.

Definitely run 9s all around with those modifications. As long as you don't drive like a grandma all of the time, you shouldn't experience plug fouling with the 9s.
