Ferrea is well-known for making strong internal engine components, and these 6000 Series valves are a great example for your Honda D16Z6, D16Y5, D16Y7, or D16Y8 engine. If you're rebuilding the top end of one of these popular Honda engines, these intake valves are designed to handle the demands of performance builds. They feature a 30mm head diameter and a 5.48mm stem, which are stock sizes, making them a straightforward replacement or upgrade for your existing setup.

The S-Flo (Straight Flow) design with radial grooves is intended to improve airflow into the combustion chamber, which can help with overall engine efficiency and power. The 20-degree valve seat angle is also a common performance feature that helps the valve seal better. These valves are built from durable materials to withstand the heat and stress inside your engine, offering a solid option for your build.
