About this part

Product Details

If you're rebuilding the top end of your Subaru FA20 engine, these Ferrea Comp Plus intake valves are a solid option. This set includes eight valves, each measuring 36mm in diameter with a 5.46mm stem and a 105mm overall length. The +1mm sizing means they are slightly larger than stock, which can help improve airflow into the combustion chamber when paired with other performance modifications.

Ferrea is known for making well-built valvetrain components, and these Comp Plus valves are no exception. They feature a flat head design and a 10-degree swirl-flow (S-Flo) tulip, which is designed to help with air velocity and mixture preparation. The material and construction are intended to handle the demands of a performance-oriented engine build, offering a durable replacement for your original valves.
