NGK Iridium Sparkplug DCPR8EIX

Go with the DCPR9eix its a colder plug runs better and I find it starts easier too

 

[gixxerjoe06]

thank you both!!

do the factor Hd plugs 10R12 IIRC suck compared to NGK any evidence or proof of this?

 

[Disturbed1]

HD 10R12 IIRC are the same as the NGK's (Harley probably buys them and stamps there logo on it)

I just put new Harley ones in my xb12, runs great now. They work, I might try NGK's next time but Harley's all I had
