Our timing plug kits allow you to replace your factory timing plugs known to break and strip out with high quality plugs. Our plugs are machined from billet aluminum, anodized, and laser etched. They have integrated hex heads to allow the use of a normal socket, which means it will be much less likely to strip out as well as being more user friendly.
Be sure to inspect your factory O-rings. You will be required to reuse them.
Fits many Yamaha models. If unsure, please don't hesitate to ask.
