Ferrea Subaru FA20 36mm 5.46mm 103.45mm 10 Deg S-Flo Flat Hd +1mm Comp Plus Intake Valve - Set of 8

If you're working on the engine for your Subaru FA20, these Ferrea Comp Plus intake valves are a solid option for rebuilding or upgrading. This set includes eight valves, each measuring 36mm in diameter with a 5.46mm stem and a total length of 103.45mm. They are designed with a 10-degree S-Flo flat head and are 1mm larger in diameter than stock, which can help improve airflow into the combustion chamber.

Ferrea is known for making well-built engine components, and these valves are no exception. They use strong materials and advanced manufacturing processes to ensure durability and consistent performance. The +1mm sizing is a common upgrade for FA20 engines looking for a bit more breathing room, especially when paired with other performance modifications. The S-Flo design helps reduce valve float at higher RPMs, contributing to smoother engine operation.

When installing these valves, it's important to ensure your valve guides and seats are in good condition. Proper installation is key to getting the most out of these components and ensuring the longevity of your engine rebuild.
