Just wondering if you should use any kind of a special spark plug when using nitrous. I have Bosch Platinums on right now but have heard that NGK's are the best? Which should I buy? Thanks

Dont use the platinums when running nitrous. The nitrous can cause the platinum coating to flake off which could result in major problems. I've heard many people recommending iridium plugs with nitrous. With anything like a 75 shot or under you'll be fine with the stock heat range plugs. Our plugs have a fairly cold heat range and going colder with a smaller shot can just cause more plug fouling than normal.
