GSC P-D Subaru/Scion FA20 BRZ/FRS/FT86 2014+ 23-8N Chrome Polish Exhaust Valve 30mm Head +1mm - (1)

This GSC Power Division exhaust valve features a 30mm head with a +1mm oversized design, specifically made for Subaru and Scion FA20 engines found in the BRZ, FRS, and FT86 models from 2014 onwards. The larger head diameter can help improve exhaust gas flow out of the cylinder, which is a key factor in engine performance. The valve itself is constructed with a chrome polish finish, offering a smooth surface that can help reduce friction and resist wear over time.

When rebuilding or modifying the top end of your FA20 engine, choosing the right valve is important. This particular valve is designed to be a direct replacement for the stock unit, but with an updated size that can contribute to better breathing. The +1mm sizing means it's slightly larger than the factory valve, allowing for a bit more volume to pass through the exhaust port. This is a well-made component from GSC Power Division, a company known for its engine performance parts.

If you're working on your FA20 engine, this exhaust valve is a solid option to consider. It's a single valve, so be sure to order the correct quantity for your engine's needs. Always refer to your vehicle's service manual or a trusted mechanic for specific installation procedures and torque specifications.
