which plugs?

[silverspeed03]

for my mods what spark plugs should I buy.

i bought the denso IK22's and they are awesome. Got about 40 more miles out of a tank of gas and the car runs extremely smoother

[Puckpimp71]

I second that

Depends on your budget.
NGK
ZFR6F-11 Copper - Affordable
ZFR6FIX-11 Iridium - Pricey

Gap to .028-.032.

Then when would I want a step colder plug, meaning after what mod?

I think after you increase boost. I'm not sure what would happen if you went a step colder on stock boost, though.

Try running a search on here. Its amazing what you will find! In fact, there is a long post about plugs at the very top of this forum! You don't even have to search!

use a step colder when you up the boost if you go a step colder on stock boost youll probably run even more rich

[silverspeed03]

(ZFR6F-11 Copper) where is a good place to get these plugs?

The plugs would most likely foul out quickly and you would waste your money.

i personally am using NGK ZFR7F-11 (speaking of which i need to change mine)Ok I'm confused, the higher the number the colder the plug is that how it goes?

[A.V.MSP]

yes

[pates03]

Well if i'm running stock boost which plug will be the best for me...i'm assuming not the ik-22 b/c of the it's a step colder

[A.V.MSP]

you could run the iridiums with the stock heat range

I run the zfr7-11 gaped to .032. I am on stock boost and the car feels good and smooth. Idle could be better but I dont think its the plugs, its more my dirty erg pipe that has to be cleaned.
