Ferrea Subaru EJ20 37mm 5.97mm 104.44mm 19 Deg S-Flo +1mm Competition Plus Intake Valve - Set of 8

Ferrea is well-known for making high-performance engine components, and their Competition Plus valves are a popular choice for Subaru EJ20 builds. This set of eight intake valves is designed to handle the demands of modified engines, offering an improved flow path thanks to their S-Flo design and a larger 37mm head diameter. The +1mm sizing means these valves are slightly larger than stock, which can help increase airflow into the combustion chamber for better performance.

These valves are built with strong materials and feature a 19-degree seat angle, a common specification that works well with many cylinder head designs. The 5.97mm stem diameter is also a standard size, making them compatible with many valve guides. If you're rebuilding the top end of your Subaru EJ20 and looking for valves that can support increased power, these Ferrea Competition Plus valves are a solid option.
