Ferrea Subaru FA20 30mm 5.45mm 95.3mm Flat Head +1mm 6000 Series Exh Valve - Single (D/S Only)

This is a single Ferrea 6000 Series exhaust valve designed for Subaru FA20 engines. It measures 30mm in head diameter and 5.45mm in stem diameter, with an overall length of 95.3mm. This valve is a +1mm oversized option, meaning it's slightly larger than stock to help improve sealing and performance in rebuilt or modified engines. It features a flat head design and is intended for the exhaust side only, specifically for the driver's side application.

The 6000 Series valves from Ferrea are well-built for demanding applications. They are constructed from high-strength materials to withstand the heat and stress of engine operation. Using an oversized valve like this can be beneficial when resurfacing the cylinder head or when building a performance-oriented engine, as it can help compensate for material removed during machining and improve the valve-to-seat seal. This particular valve is a single unit, so you'll need to order the correct quantity for your engine build.
