Can anybody tell me the difference between these and ordinary nova rossi plugs?
I thought the ULTRA plugs have been there all along...
Anyway, the ULTRA plugs is suppose to last longer due to a more superior filament coil and they are more expensive. You can identify them with the 2 grooves on the top where the plug makes contact with the glow ignitor. Ordinary turbo plugs are with one groove.
