What material are these intake valves made from?

These Manley Race Series intake valves are constructed from high-quality stainless steel. This material is chosen for its durability and resistance to wear, especially in high-performance engine applications.

What is the benefit of the swirl polished and machined combustion face?

The swirl polished under head areas and fully machined combustion faces are designed to improve airflow into the cylinder and enhance combustion efficiency. This helps the engine perform at its best.

Are these valves suitable for use with alcohol-based fuels?

While Manley recommends these stainless steel valves for exhaust valves in alcohol engines, they are primarily designed as intake valves for high-RPM gasoline applications. For specific fuel compatibility, it's always best to consult the manufacturer's detailed specifications.

About this part

Product Details

If you're rebuilding the top end of your Nissan RB26DET(T) engine, these Manley Race Series intake valves are a solid option. They're built from stainless steel, which is key for durability, especially when you're pushing the engine hard. The 35.6mm Race Flo shape is designed to help optimize airflow into the combustion chamber, which matters a lot for getting the most out of your 2.6L inline-6.

Manley puts a lot of care into these valves. They've got chrome stems and hard tips to help them hold up to wear over time, and the under-head area is swirl polished to smooth out airflow. The combustion face is also fully machined, which helps improve how efficiently the air and fuel mix burns. These are built for engines running up to 8000 RPM, so they're made to handle some serious action on the track or the drag strip.
