spark plugs for nitrous
 

I'm going to shoot a 75 shot of nitrous in my nismo but I'm not sure what heat range of spark plug to get. Can somebody help me out.

The heat range in stock spark plugs is ok, I didn't change them in my Z and a it's ok with 75 shot. Generally, in teory we should change the spark plugs for one step colder, iridium plugs, but those in my Z was the same as in the GTR's, and the heat range was good. Watch out for the clutch, because the torque is big during the shot and I suggest changing the stock clutch for something stronger.
