Ferrea Acura K20 31mm 5.45mm 109.15mm +1mm Flat Head 5000 Series Exh Valve - Single (Drop Ship Only)

If you're rebuilding the top end of your Acura K20 engine, especially for a performance build, you'll want to make sure your valves can handle the extra stress. These Ferrea 5000 Series exhaust valves are a solid option for that kind of work. They're made from a strong, heat-resistant alloy that's built to last under demanding conditions.

This particular valve is a single, flat head exhaust valve measuring 31mm in diameter with a 5.45mm stem and a 109.15mm overall length. It's a +1mm size, meaning it's slightly larger than stock, which can help improve airflow into the cylinder. Ferrea is known for making well-built valvetrain components, and these valves are a popular choice for tuners and engine builders looking for reliable performance.
