Ferrea Subaru FA20 30mm 5.45mm 95.3mm Flat Head +1mm Super Alloy Exh Valve - Single (D/S Only)

This listing is for a single Ferrea Super Alloy exhaust valve designed for Subaru FA20 engines. You get one exhaust valve with a 30mm head diameter, a 5.45mm stem, and a 95.3mm overall length. This valve is 1mm larger than stock and features a flat head design, intended for the driver's side (D/S) of the engine.

Ferrea uses a special super alloy for these exhaust valves, chosen for its ability to withstand the high temperatures and stresses found in performance engine applications. The +1mm sizing can help improve airflow when paired with other engine modifications, and the flat head design is a common choice for many performance builds. This valve is built to be a direct replacement for the stock unit, making installation straightforward if you're rebuilding or upgrading your FA20 engine.
