Product Details

Starting with a 35.5mm head diameter, these Manley Race Flo intake valves are built for your 1993-2001 Honda Prelude with the 2.2L DOHC VTEC engine. They are constructed from high-quality stainless steel, chosen for its durability under the stress of racing conditions, especially for engines running up to 8000 RPM.
