NGK TR6 Plug Question Hey guys. Weight question
I have had NGK TR6 plugs in my car since 2017. Car did have longtubes headers, and a tune (timing/fuel adjustments etc). Plugged the plugs out in 2022, and plugs looked fantastic. I have recently changed exhaust to stock manifolds and Y pipe/cats, along with a freshly flashed OEM PCM. I just put fresh TR6 Platinum plugs in the car 2 weeks before all this occurred.
If I had no issues before, but have changed back to stock tune and exhaust - should I leave them in there and just run them until next plug change... or pop in some TR55's over the winter (seems wasteful).
Let me know, thanks!
