Manley Volkswagen 1.7L 40mm Dia 4.606in Length Race Series Exhaust Valve Kit

Manley Performance is well-known for making strong internal engine components, and their Race Series valves are a prime example. This exhaust valve kit is built for demanding applications, like bracket, drag, and oval track racing, especially for engines running under 8000 RPM. If you're rebuilding the top end of your Volkswagen 1.7L, these valves are designed to handle the heat and stress.

These exhaust valves are made from a tough stainless steel that holds up well over time. They also feature chrome stems and hard tips, which add to their longevity and resist wear. The under-head area is swirl polished and the combustion face is fully machined. This design helps improve airflow into the cylinder and can contribute to better combustion efficiency. They're also a recommended choice for alcohol-fueled engines, offering reliable performance when you need it most.
