What makes these valves 'Extreme Duty'?

These valves are constructed from XH-432 XtremeAlloy, a material chosen for its exceptional strength and resistance to extreme heat and force. They are built to handle demanding applications beyond typical street use.

What are the benefits of the chrome stems and hard tips?

The chrome stems and hard tips are incorporated to significantly improve the longevity and wear resistance of the valve. This means they can withstand more cycles and harsher conditions before showing signs of wear.

Does this valve come individually or as a set?

This listing is for a single Manley 32mm stainless steel exhaust valve. You will need to order the appropriate quantity for your engine's cylinder head configuration.

About this part

Product Details

If you're rebuilding the top end of your 2005 Saab 9-2X, especially if you're pushing the limits of the EJ20 engine, you need exhaust valves that can handle the heat and pressure. These Manley Extreme Duty valves are built for demanding situations, offering a significant upgrade over stock components. They are made from XH-432 XtremeAlloy, a material known for its exceptional strength and resistance to extreme temperatures, making them a solid choice for high-performance builds.

Manley has incorporated several design features to optimize performance and durability. The valves have chrome stems and hard tips, which add to their longevity and resistance to wear, even under harsh operating conditions. The under-head areas are swirl polished to help improve airflow into the combustion chamber, and the combustion faces are fully machined for better efficiency. These details contribute to a more consistent and powerful engine operation.
