FULL DESCRIPTION
ProX Steel Intake Valve and Spring Kit
Upgrade your motorcycle's performance and durability with the ProX Steel Intake Valve and Spring Kit. This kit is designed to replace your OEM titanium valves with robust steel valves, significantly extending the lifespan of your engine components.
