Ferrea Subaru EJ20 37mm 5.97mm 104.6mm 19 Deg S-Flo Radius Grv +1mm 6000 Series Int Valve - Set of 8

Ferrea is well-known for making high-performance engine components, and these 6000 Series valves are a prime example of their work. If you're building or rebuilding a Subaru EJ20 engine, these intake valves are designed to handle the demands of a performance build.

This set includes eight intake valves, each featuring a 37mm head diameter and a 5.97mm stem. They are designed with a +1mm oversized head, which can help improve airflow into the combustion chamber. The S-Flo radius groove design is a notable feature that helps promote better gas flow. These valves are made from Ferrea's 6000 Series alloy, chosen for its strength and durability under high temperatures and pressures common in performance engines.

When installing these, remember they are a +1mm oversized valve, meaning the valve seat may need to be re-machined to properly accommodate the larger head diameter. This ensures a good seal and optimal performance for your EJ20 build.
