Customer Reviews

Ride on

By Travis B. on  Verified Purchaser

Great parts

Awesome Plugs!

By Steve G. on  Verified Purchaser

Installed these plugs in my 2020 Honda Fury to complete my initial maintenance after buying the bike. As soon as I started it...the engine ran much smoother...and when I took it out for a ride...the improvement in acceleration and power was noticeable. No doubt which plugs I'll run...

No better(or worse) than standard plug it replaced

By John C. on  Verified Purchaser

Seems like a decent plug but for the extra money it cost over the "standard" plug it replaced, my ATV doesn't seem to run any different-for better or worse. I'll probably just stick with the much cheaper, standard NGK plug next time.

Great quality

By Michael D. on  Verified Purchaser

Pre gapped plugs factory replacement parts great quality

Use these

By Ron M. on  Verified Purchaser

Definite improvement over the OEM plugs will be my go-to from now on.
