About this part

Product Details

This Ferrea 5000 Series exhaust valve features a 31mm head diameter and a 5.48mm stem, measuring 107.1mm in overall length. It's designed as a +1mm oversized valve, meaning it's 1 millimeter larger in diameter than the stock valve, which can help improve airflow into the cylinder. This specific valve is intended for the exhaust side only and is a single unit, often used when replacing individual damaged valves or for specific performance builds.

The 5000 Series from Ferrea is known for its well-built construction, using high-grade materials suitable for demanding engine conditions. The flat head design is a common choice for exhaust valves, balancing performance with durability. When rebuilding or modifying your Honda H22A1 or H22A4 engine, using valves that meet precise specifications is crucial for proper sealing and performance. This valve is a direct replacement for the stock exhaust valve, but its +1mm sizing means it requires a compatible valve seat to match the larger diameter.
