They are indeed sparkplugs

Posted by Caden on 18th Jun 2023

Probably over priced. They came mostly adjusted in spec for use with my 1980 CB750F, but they didn't come with the screw caps that my ignition coils need. I was able to just use the old ones, but just something to make not of.

Iridium spark plugs

Posted by Rich on 25th Dec 2020

Bought a set for my '76 cb400/4 and my '78 cb750/4. Never thought a set of plugs could make such a difference. Bikes don't skip a beat now and start much easier. Well worth the price
