Installed NGK 6510 plugs when I added boost and gapped them at .026". I have 16K with FI and took a buddy for a spin a few weeks ago. Got a CEL. Code P300, random misfires. Plugs looked pretty worn upon inspection.
Installed new 6510's at the same gap. No codes during a test run. But I would almost bet the car felt like it picked up 30+ horsepower. It pulled really hard. Spins my Nitto 555R's at anything under 55 mph with a hard hit.
So I am sharing this if you have been running your plugs for over 15K it might be time to change. Going to change them at around 10K from now on.
