Show original supplier description
This recirculating version of the legendary TiAL Q BOV ensures an efficient connection to your vehicle's air inlet system. It boasts a substantial 51 MM (1.98'') valve diameter, capable of a mass flow rate of 31 LB/MIN and operating within a pressure range of 2 to 12 PSI. Engineered entirely in-house by TiAL's dedicated team, the QR Series BOV is constructed from premium, all-billet aluminum. To ensure longevity and reduce wear on mating parts, the valve stem and guide undergo a specific, rigorously tested anodizing process. This meticulous construction guarantees durability and reliable performance under demanding conditions. Included with each QR BOV assembly are an air fitting set, weld flange, clamp assembly, and weld flange O-ring. Specific actuator color, spring rating, and outlet connection must be specified at the time of order to ensure proper fitment and function for your application.
