Ferrea Acura K20 31mm 5.45mm 109.15mm 22 Deg Flo Radius Grv +1mm 6000 Series Exhaust Valve- Set of 8

These Ferrea 6000 Series exhaust valves feature a 31mm head diameter and a 5.45mm stem, designed for specific performance applications in Acura K20 engines. The 22-degree 'Flo Radius' groove is a notable design choice that helps improve airflow into the combustion chamber, especially at higher RPMs. This updated groove profile is part of Ferrea's ongoing efforts to refine valve performance.

Constructed from Ferrea's 6000 Series alloy, these valves are built to handle the increased stress and heat found in performance-oriented K20 builds. The valves are 109.15mm in overall length and are manufactured to a +1mm oversize, which is important to note if you are rebuilding or modifying your cylinder head. This specific sizing ensures a proper fit and seal within the valve guide and seat.

When you're working on a performance K-series engine, using well-made components like these Ferrea valves can make a difference in how reliably your engine performs under demanding conditions. They are a solid option for builders looking for components that are designed to meet the challenges of modified engines.
