I've never read a spark plug before so I don't know if my engine running rich or lean. Thank you

those look a little lean

and a hint for next time
dont waste money on those stupid 4 tipped plugs.
the stock NGK ones work best.

 

Man those are like the worst plugs u could have put in your car.

 

They don't look all that bad, maybe a tad bit lean but from these pics I don't see any detonation, etc... You wouldn't happen to know which one came from which cylinder because they vary a little meaning that you could be dropping FP across the rail... Are you running an aftermarket FPR?? It looks like some stay rich a little higher up the rpm band, but you should be fine... I would just drop some NGK 6's or 7's in there... Peace

 

thanks guy. I already changed to NGK cbr7es-11 to run nitrous. I had these back when I just did the swap. I didn't know much about plugs.

 

white is lean black is rich
