Supertech Subaru WRX 2.0L/2.5L 33.0x5.96x104.20mm Inconel + 1mm Dia Exhaust Valve- Single (D/S Only)

If you're rebuilding the top end of your Subaru WRX with a 2.0L or 2.5L engine, especially for performance applications, you'll want to pay close attention to your exhaust valves. This Supertech exhaust valve is made from Inconel, a material known for its exceptional heat resistance and strength, making it a solid choice for demanding engine conditions. The valve measures 33.0x5.96x104.20mm and is 1mm larger in diameter than stock, which can help improve exhaust flow when paired with other engine modifications.

Using Inconel for exhaust valves is a smart move because these components are subjected to extreme temperatures and pressures as exhaust gases exit the combustion chamber. This material holds up better under those conditions than standard steel, reducing the risk of valve distortion or failure. The slightly larger diameter is a common upgrade for tuners looking to extract more power, as it allows for a bit more volume to pass through the exhaust port. This specific valve is for the driver's side (D/S) only, so be sure to order the correct quantity for your application.
