I want some real good spark plugs I hear ngk iridiums heat rating 7 are nice and wont burn a whole in my pocket next I was considering the spark plug grounding rail that ive seen online does this make that much of a difference?

I want some posts and suggestions as to what spark plugs I should get and next what grounding kits I should buy.

Also another thing any of you ever consider upgrading your radiator is it necessary?

I have a hook up for radiators but mine seems to work fine?

Post some links to where I can get a good deal on spark plugs if you guys have any thanks and much appreciated.

 

Didn't you say that you're running low boost with no EMS? I'd start there, buy an eManage and up the boost.

 

I bought the CAMCON unit i need to tune up my car after the dyn tunes are done i want to change spark plugs oil etc..
