Manley 92-00 Acura Integra / 99-00 Honda Civic 16 Valve 28.0mm Race Flo Exhaust Valve (Set of 8)

If you're rebuilding the top end of your 1992-2001 Acura Integra or 1999-2000 Honda Civic, these Manley Race Flo exhaust valves are a solid choice. They are specifically designed for engines that see a lot of action, like those used in bracket racing or drag racing, and are built to handle up to 8000 RPM. These are the exhaust valves you'll want if you're running alcohol fuel, as they're recommended for that application.

Manley makes these valves from a strong stainless steel, which means they'll hold up well over time. The stems are chrome-plated and the tips are hardened to resist wear, giving you more miles and more passes before you need to worry about them. They've also been swirl polished under the head and fully machined on the combustion face. This helps the air and fuel mixture move more smoothly into the cylinder, which can lead to a more efficient burn and better overall engine performance. The Race Flo shape is designed to optimize airflow for specific racing setups.

This set includes eight exhaust valves, which is what you'll need for a 16-valve engine. Make sure to check the manufacturer's installation instructions for any specific details regarding valve seating and break-in procedures.
