Supertech Subaru WRX 2.0L 33x5.96x104.20mm +1mm Dia Blk Nitride Exhaust Valve - Single (D/S Only)

If you're rebuilding the top end of your Subaru WRX's 2.0L engine, especially if you're looking to replace worn or damaged exhaust valves, this Supertech valve is a solid option. It's designed as a single exhaust valve, specifically for the driver's side, and measures 33x5.96x104.20mm with a +1mm diameter increase over stock.

This valve features a black nitride coating, which helps improve its surface hardness and wear resistance. The +1mm sizing means it's slightly larger than the original, which can be useful if you're dealing with worn valve seats or need a bit more sealing surface. It's a well-built component intended to handle the heat and stress of the exhaust cycle.

When installing, remember that exhaust valves work in conjunction with the valve seat and spring to control the flow of gases into and out of the combustion chamber. Ensure all mating surfaces are clean and properly seated for optimal performance.
