Figured I should post up a thread to see what everyone is running for plugs on their built motor / turbo cars as we don't have an up-to-date thread.

 

I think this has been covered before, try searching. Plugs depend on the motor/setup.

In general I prefer NGK Iridium's for the 350Z. 1 step colder will suit many street builds, and 2 step colder for more extreme setups.

NGK 1step colder

NGK 2step colder

 

ya 2 step are nice

 

i have 1 step here.

 

600hp...1 or 2 steps? I know if you go too cold the plugs wont "self clean" and fowl up quick.

 

for fi go with NGK Iridium's 1 step cold Napa should have them in stock At napa you have to buy a box of 8 though.
Nitrous go with NGK Copper 1 step or 2 step cold

 

2-Step Colder NGK's!

I've used both NGK 1 step iridium and NGK 1 step copper...not much difference IMO

 

+1...I use the same.

 

NGK Copper, 1 step colder
