Great racing plug, great service!
Have not had a chance to try them.
This sparkplug has cost me more than its worth.
Bought it and installed it into a custom engine I've been working on for awhile. I've used it for approximately for about 4 hours till it stopped working, I've found carbon climbing up the ceramic through the nut. I thought nothing of it and thought it was my head failing, I've had the valves seated twice at a machine shop, $300's later I threw a stock sparkplug on it and the engine ran fine. I don't know whether I got a bad batch. But either way I'm not a fan.
think I need a carb
