What is the main benefit of using these 31mm intake valves?

The primary benefit is improved airflow into the combustion chamber due to the larger 31mm valve head diameter compared to stock. This can contribute to increased engine performance, especially in modified engines.

Do these valves come with everything needed for installation?

This product includes the 31mm intake valves themselves. You will need to ensure you have compatible valve springs, retainers, seals, and potentially valve guides, as these are not included with the valves.

What type of steel are these valves made from?

The valves are constructed from durable steel. While the specific alloy is not detailed, steel construction is chosen for its strength and ability to withstand engine operating temperatures.

Product Details

Brian Crower is known for making well-built internal engine components, and these 31mm intake valves for Honda and Acura B-series engines are no exception. If you're working on a B18A, B18B, or B20B engine, these valves are designed to help you get more air into your cylinders. They are a direct replacement for your stock intake valves, but with a larger 31mm head diameter, they can help improve airflow into the combustion chamber, which is key for making more power.

These valves are made from durable steel and are built to handle the demands of performance-oriented builds. When you're rebuilding the top end of your engine, using quality valves like these can make a notable difference in how your engine breathes. They are designed to fit right into the stock valve seats, making installation straightforward for anyone familiar with engine assembly. Just be sure to check your valve guide clearances and ensure your valve springs are up to the task of handling the increased airflow and potential for higher RPMs.
