Manley 92-00 Acura Integra / 99-00 Honda Civic 16 Valve 33.5mm Race Flo Intake Valves (Set of 8)

Starting with a 33.5mm head diameter, these Manley Race Flo intake valves are built for performance in your 1992-2001 Acura Integra or 1999-2000 Honda Civic. They are constructed from durable stainless steel, specifically NK-842 for the intake side, which holds up well under the heat and stress of an engine. The stems are chrome-plated for added wear resistance, and the under-head areas are swirl-polished to help smooth out airflow into the combustion chamber.

These valves are fully machined, including the combustion faces, to ensure they seal properly and contribute to efficient combustion. The Race Flo shape is designed to optimize airflow for engines operating under 8000 RPM, making them a solid choice for bracket, drag, or oval track racing applications. If you're rebuilding the top end of your engine and looking for improved airflow, these valves are a well-built option.

This set includes eight intake valves, enough for a typical 16-valve cylinder head. While these are recommended for alcohol engines on the exhaust side, they are a strong choice for intake valves in many performance applications.
