GSC P-D 2015+ Subaru FA20F WRX Chrome Polished Exhaust Valve - 30mm Head +1mm - Set of 50

This set includes 50 GSC Power Division exhaust valves, each featuring a 30mm head and a +1mm oversized stem. These valves are specifically made for the 2015 and later Subaru FA20F WRX engine. When you're rebuilding the top end of your engine, especially for performance applications, the exhaust valves are critical components that handle extreme heat and pressure. Choosing the right valves ensures proper sealing and efficient exhaust gas flow, which directly impacts engine performance and longevity.

These GSC Power Division valves are constructed from a chrome polished material, designed to withstand the harsh environment within the combustion chamber. The +1mm oversized stem is a notable detail, often used when reconditioning cylinder heads to ensure a perfect fit and seal in the valve guides, especially if the guides have been honed or replaced. The 30mm head size is a common specification for this engine, balancing flow capacity with proper piston clearance. Having a set of 50 means you have enough valves for multiple engines or for a comprehensive rebuild project.

Proper installation is key to getting the most out of these valves. Ensure your cylinder heads are clean and the valve guides are within specification before installation. These valves are intended for performance builds where reliability and consistent operation under demanding conditions are important.
