About this part

Product Details

When you're rebuilding the top end of your 1990-1996 Nissan 300ZX, especially for racing applications, you need parts that can handle the stress. This set of Manley Race Flo intake valves is designed for engines that see a lot of action, operating reliably even above 8000 RPM.

These intake valves are constructed from high-quality stainless steel, giving them solid durability for demanding use. They feature chrome stems and hard tips to resist wear over time, and the under-head areas are swirl polished to help optimize airflow into the combustion chamber. The fully machined combustion faces also contribute to better airflow and combustion efficiency.

Manley offers these valves in a Race Flo shape, which is a good choice for specific racing engine setups. If you're running an alcohol-based fuel, these are also recommended for exhaust valves, though this specific part is for intake. Make sure you have the correct valve seals and guides to go with them for a complete rebuild.
