Ferrea Subaru FA20 36mm 5.46mm 105mm Flat Head +1mm Comp Plus Int Valve - Single (Drop Ship Only)

Ferrea Subaru FA20 Comp Plus intake valves are a solid option when you're rebuilding or upgrading the top end of your Subaru's FA20 engine. This particular valve is designed with a 36mm flat head and measures 105mm in overall length, featuring a 5.46mm stem diameter. It's a +1mm oversized valve, meaning it's slightly larger than stock to help improve airflow into the combustion chamber.

Ferrea is known for making well-built valvetrain components, and these Comp Plus valves are made from strong materials to handle the demands of performance applications. The +1mm sizing is a common choice for tuners looking for a bit more breathing room for the engine without requiring extensive head modifications. Remember that when installing oversized valves, you'll want to ensure proper valve seat machining and clearance checks are performed by a qualified technician to guarantee optimal performance and longevity.
