Pro Circuit's titanium valves are developed by in-house technicians and manufactured to stringent specifications by Del West, the industry leader F-1 racing valve technology.
Every intake and exhaust valve is CNC machined and precision ground using only the finest light weight titanium available. To increase performance, durability and reduce wear a thermally sprayed nitrate coating is applied to the stem and valve head creating a finished product that is second to none. Intake and exhaust valves are sold in pairs.
