Has anyone here used NGK Racing plugs in a ka or ka-t?
There good! Why?
Just wondering if they are worth the extra money.
if you have a stock ka u dont need to go all out and get the best plugs out there they will last longer though, but if u have a ka-t im sure u wana run something better with higher heat range so u dont keep blowing the plugs. but yeah for stock get something decent, no need to get the expensivest plugs becuase u wont notice much of a dif.
