Improved Racing Adjustable PCV and Turbo Oiling Restrictor Valves
Replace your traditional PCV valve with Improved Racing adjustable PCV restrictor valves for better reliability and increased crankcase vacuum. They are perfect for LS engines with aftermarket valley covers that do not have a built-in PCV restrictor like the factory cover, and they can also restrict oil flow to a turbocharger to avoid flooding the turbo. Improved Racing's restrictor valves can be used on their own, replacing traditional PCV valves in naturally aspirated engines, or combined with a check valve to prevent pressurizing the crankcase under boost in turbocharged applications. Features and benefits: * Adjustable PCV restrictor with 5 pre-drilled sizes: -- 2.6mm, 3.0mm, 3.5mm, 4.0mm, 4.5mm -- Plus, a blank disc with a 1mm pilot hole for custom-drilled sizes * Female -6 O-ring boss ports on each end -- Can be adapted to many different fitting types and sizes (male AN, hose barb, quick connect, etc.) * All-aluminum 6061 T-6 construction with black Type II anodized housing * Each plate is laser-marked with the restrictor hole diameter in millimeters * No moving parts for improved durability over traditional PCV valves
