Default Ngk Tr55ix
Is anyone running these plugs? Are they better than NGK TR55's? Are they worth it?

Thanks in advance

Great plugs, especially with nitrous...although I'd run the colder TR 6ix's on the gas. They're what I run in my car.

TR6ix plugs are ideal for nitrous. TR55ix plugs are ideal for running on motor. Iridium lasts as long as platinum, but will survive the high heat of a nitrous motor even better than a conventional copper plug.

Stock gap of the TR6ix's is around .038". That's a good place for a dual/purpose nitrous motor.

any news on this thread? did you end up getting the TR5ix's ?????

What about not gapping them at .044" like NGK.com says? Just because of the spray? How much you spraying?
