Supertech Subaru EZ30 H6 (2nd Gen) 30.5mm Head Diameter Inconel Exhaust Valve - Set of 12

This set includes 12 Supertech Inconel exhaust valves, each with a 30.5mm head diameter, specifically made for Subaru EZ30 H6 (2nd Gen) engines. These valves are crucial for managing the hot exhaust gases leaving your engine, and using the right material can make a big difference in how long they last, especially in high-performance or heavily modified applications.

Supertech chose Inconel for these exhaust valves because it's a well-known material for its exceptional resistance to high temperatures and corrosion. Exhaust valves operate under some of the harshest conditions in an engine, constantly exposed to extreme heat and combustion byproducts. Inconel's properties help prevent valve distortion, burning, and premature wear, which can lead to compression loss and engine damage. The 30.5mm head diameter is a specific measurement designed to match the factory port size and valve seat on the EZ30 H6 engine, ensuring a proper seal and efficient gas flow. This set is designed to replace all the exhaust valves in your engine, providing a complete solution for a rebuild or performance upgrade.

When rebuilding an EZ30 H6 engine, especially if you're pushing the limits or dealing with higher cylinder pressures, upgrading to Inconel exhaust valves is a smart move. They offer a significant improvement in durability over standard materials, helping to ensure the longevity and reliability of your engine's top end. Make sure to follow the manufacturer's installation instructions carefully when fitting these valves to ensure optimal performance and longevity.
