Manley Acura/Honda (B16A1/B16A3/B17A1/B18C1-C3) 28.5mm RaceMaster Exhaust Valve (Set of 8)

If you're rebuilding the top end of your 1992-2001 Acura Integra, especially if it's seeing regular track time or operating above 8000 RPM, you'll want to consider these Manley RaceMaster exhaust valves. These are designed to handle the heat and stress that come with performance engine builds, ensuring your engine breathes efficiently and reliably.

Manley makes these valves from a high-quality stainless steel, which is crucial for exhaust valves that deal with extreme temperatures. They've also added chrome stems and hard tips to make them last longer and resist wear, even with frequent use. The under-head area is swirl polished and the combustion face is fully machined. This helps improve airflow into the cylinder, which can make a noticeable difference in how your engine performs, especially when you're pushing it hard.

This set includes eight exhaust valves, which is what you'll need for your B16A1, B16A3, B17A1, or B18C1-C3 engine. They're a solid option if you're building an engine for drag racing, oval track, or even just a spirited street build that sees a lot of action.
