Ferrea Subaru FA20 30mm 5.45mm 95.3mm 29 Deg Flo Flat Head +1mm Super Alloy Exhaust Valve - Set of 8

These Ferrea exhaust valves are built from a super alloy, a strong material chosen for its ability to handle high temperatures and pressures found in performance engines. Each valve measures 30mm in diameter with a 5.45mm stem and a 95.3mm overall length, and they are designed with a +1mm oversized head to improve airflow into the combustion chamber. The 29-degree flo flat head design further aids in efficient gas flow, making these a solid choice for rebuilding or upgrading the top end of your Subaru FA20 engine.

When you're rebuilding the top end of an engine, especially one like the Subaru FA20 that can benefit from improved breathing, using well-built valves is crucial. These Ferrea valves are made from a high-performance super alloy that resists the extreme heat and stress of combustion. The +1mm oversized head is a notable change from stock, designed to increase the valve's sealing surface and allow more air-fuel mixture into the cylinder, which can lead to improved performance. The 29-degree seat angle is also part of the design to promote better flow characteristics.

This set includes eight valves, enough for a complete engine. If you're working on a performance build or a thorough engine overhaul for your Subaru FA20, these valves offer a step up in material strength and airflow potential over standard components.
