Manley Pro Flo 29 mm intake valves for 1988–1991 Honda Civic/CRX Si are part of Manley’s Race Series engineered for engines operating up to 8,000 RPM. These intake valves are swirl-polished beneath the head, fully machined at the combustion face, and made from stainless steel for durability. Chrome stems and hard tips enhance longevity, and a choice of valve shapes lets builders match valve geometry to specific high-RPM applications.
