I just wanna know if my ngk iridium plugs are still good or not also if I should stick with the NGK iridium or copper plugs which is better?

 

those looks fairly new to me by the pictures

 

that's what I thought but I just wanted a second opinion

 

look new and a slight bit lean, i think it should be a bit more brown

 

Those look new. Don't forget the anti-seize.

 

They look like they still have the sharps edge on the electrode...and the therefore look new to me as well but as far as it looking like it was burning lean....No that's the flash of the camera in the 2nd pic....The 1st pic the color is perfect (kinda light chocolate), Clean your threads in the head (with a sparkplug thread chaser smeared with ball bearing grease to keep minimum debris from falling in your combustion chamber...Spray a little brake cleaner in all the spark plug holes once all 6 threads are chased and turn over engine a few revolutions to blow out any debris that may have fall down in the chamber... And apply antiseize to your plug threads!
