I just recently bought the Zex kit for my 2.2 eco and was told to buy one step colder spark plugs, what kind of plugs should i get? (copper, plat..etc)?
Im a Xbox 360 fanboy...and damn proud of it!!
Here are your choices from NGK:
One stage colder :

Two stage colder :
ltr7ix-11 stock no. 6510

I do believe Copper is what you want
copper and 1 to 2 stages colder depending on the size of shot you'll be running. No point in buying expensive plugs, The cheap ones do the trick just fine and in Power Adder situations will outlast any platinum or iridium plug.

Depending on your shot i believe you have to retard the timing
they speak the truth, im running autolites 2 steps colder and they have lasted a long time.
autolites ftw (for nitrous anyway)

im pretty sure platinums are abd for nitrous. but maybe iridiums are good.
