ORIGINAL: cavediver

Like Goldenpony, I changed out my factory 2-piece plugs and installed the Champion #7989's in my GT. I followed the TSB and had zero problem pulling the originals out. Since I'll probably pull my Champions out and check them once a year I applied a very light coat of anti-seize to the threads and to the upper 1/3 of the ground shield. The TSB doesn't call for applying anti-seize to the threads but that is standard practice for me (and many others) any time I change plugs in an aluminum head engine. That way the plugs always slide right out.

As for the Champions, they work every bit as good or better than the original OEM's. They actually seem to have better throttle response but that could just be in my head. I'm convinced that the few who have had problems with the Champions either got anti-seize on the electrode tip or cracked the porcelain when tightening them down. They are a quality plug.
