What material are these Brian Crower exhaust valves made from?

These exhaust valves are constructed from a high-temperature alloy. This material is chosen to withstand the extreme heat and stress found in performance engine applications.

What is the benefit of the 31mm valve size?

The 31mm diameter allows for a larger volume of exhaust gases to exit the cylinder. This can contribute to improved engine performance, especially in modified or high-performance K-series engines.

Do these valves come with valve springs or retainers?

This product listing is for the Brian Crower 31mm exhaust valves only. Valve springs, retainers, and other related components are sold separately.

Product Details

These Brian Crower 31mm exhaust valves are made from a strong, high-temperature alloy, specifically chosen to handle the demands of performance K-series engines. If you're rebuilding the top end of your 2004-2008 Acura TSX, or looking to get more out of your K20A2, K20A, or K24A2 engine, these valves are a solid choice for improved airflow and durability.

The 31mm diameter is a common upgrade for these K-series engines, allowing for a greater volume of exhaust gases to exit the combustion chamber. This can lead to better performance, especially when paired with other engine modifications. Brian Crower is known for making well-built internal engine components, and these valves are no exception. They are designed to fit right into the stock valve seats for most K-series applications, simplifying installation for your engine build.

When working on your engine's cylinder head, ensuring proper valve seating and sealing is critical. These valves are manufactured to tight tolerances to help achieve that. If you're aiming for increased horsepower and torque, especially in naturally aspirated or boosted setups, upgrading your exhaust valves is a key step.
