are my plugs any good?

 

Do you use any fuel injector cleaner or octane booster?

 

Not at all. Does it have signs of detonation or something? Cant seem to find a pic that is closes to mine on spark plug reading charts.

 

The red is usually caused by fuel additives (either poured in the tank or by using lower quality fuel at some gas stations) but it doesn't have any indication that your engine is having any issues. The reason I guessed additive was that I used to change a neighbors plugs a few times a year because she kept using these "miracle" fuel pills that supposedly increased her mileage. I think what they essentially did was increase combustion temps which in the end wore out her plugs twice as fast. But her plugs were red like yours and in some cases almost purple.

 

It looks good to me, are the rest the same?
