The one on the far right looks a little dirtier then the other but otherwise ok.

Hard to tell from those pics…are the silver flecks present metallic, or something else? If so, it could be signs of detonation…otherwise, they are running pretty clean from what I can see.

I think thats copper anti-seize. I put it on the threads of my GEN II when I did the plugs and wires this spring.

Yep, used antiseize last time, not again . Two were not torqued down properly. Just going to put a tiny bit of clean engine oil on the threads.

All cathodes and electrodes are identical across all ten.

Doing some other work and changed the spark plugs out while I had valve covers off and headers off the driver’s side. Not more than 8K miles on these I would guess, since it has not been that long since I changed these…about a year. How do these look to you guys? School me please. Also, while I am ashamed to admit it, apparently I did not torque the one in the rear properly as it was just a bit more than hand tight. 🙁

These are Bosch plugs in the picture, going back to OE Champion plugs this time.

We still doing .05 gap as per spec? No FI, just bolt on mods, 2008…
