Optimize Your EJ20 Intake Flow

Unlock the breathing potential of your Subaru EJ20 cylinder heads with the Ferrea 6000 Series 36mm Intake Valves. Designed to meet the demands of modern performance tuning, these valves ensure that your engine receives the maximum amount of air-fuel mixture possible. By utilizing Ferrea’s signature S-Flo technology, these valves minimize flow restriction, allowing for a more responsive and powerful engine across the entire RPM band.

Key Technical Features

• Optimized Geometry: The 36mm head diameter combined with the S-Flo radius groove promotes superior laminar flow into the combustion chamber.
• High-Strength Alloy: Built from 6000 Series material, these valves are significantly stronger than OEM, preventing stem stretch and head fatigue.
• Precision Fitment: Engineered specifically for the EJ20 platform to ensure seamless integration with existing valve guides and seats.
• Performance Focused: Ideal for naturally aspirated builds or high-boost turbocharged applications where valve train stability is paramount.

For Subaru owners looking to push their EJ20 engine, the valve train is often the limiting factor. Replacing your stock valves with Ferrea 6000 Series components provides the peace of mind that your engine can handle increased boost pressures and higher RPMs without compromise. These valves are the gold standard for enthusiasts who refuse to settle for anything less than professional-grade performance.
