Ferrea Subaru FA20 30mm 5.45mm 97.6mm Flat Head +1mm Super Alloy Exh Valve - Single (D/S Only)

This is a single Ferrea exhaust valve designed for Subaru FA20 engines. It features a flat head design with a +1mm oversized diameter, measuring 30mm at the head and 5.45mm at the stem, with an overall length of 97.6mm. The valve is constructed from a super alloy material, chosen for its ability to withstand the high temperatures and stresses found in performance exhaust applications.

The super alloy construction offers improved durability and resistance to heat compared to standard materials, which is crucial for exhaust valves that operate under extreme conditions. The +1mm oversized head is a common modification for performance builds, as it can increase airflow into the cylinder, potentially leading to improved engine performance. This specific valve is intended for the driver's side (D/S) application only.
