I'd use just stock if your car isn't modded much.

NGK I think, that is all I have heard of thus far...you can go all 9s or use the 7s and 9s

7's leading and 9's trailing?? or vica versa?? i want to use the NGK RACE PLUGS I ONLY HAVE MIDPIPE AIR INTAKE FILTER AND DOWNPIPE, I JUST WANT TO HELP MY PERFORMANCE A LITTLE MORE BY USING THE RACE COLD PLUGS PART #IGR6725-105 WHAT DO YOU GUYS THINK??

I believe taht is right, I would have to check though. Umm...does anyone know what benefits besides reduced risk of detination that runnning all 9s gives you?

All 9's, BUR9EQ. Or you can get the platinum ones, which are more expensive.

What does the 9 and 7 stand for anyway?

How much heat the plugs discipate. The higher the #, the colder the plugs and the less heat they retain. Colder plugs foul quicker and need to be replaced sooner.
kam: Stick with 9's all around.

I have 9's as you can see, along with my mods, in my sig. I say go for them. NGK, around $9 bucks, dont go for something too expensive unless you have money to be replacing them frequently.

platinum ... there is a way to get less power ....

7,9,10.5,11 all refer to heat range-higher the number the lower the heat range and less likely to detonate.

Get the NGK race plugs or search the single turbo forum to really learn more.
