Boundary Billet Back Plate Nissan VQ VHR 3.5L 3.7L Steel Anti-cavitation High Flow

Our Billet pump covers use advanced CFD simulation and exacting 3D precision milling to create a blend of engineering and manufacturing that produces less leak by, less aeration, less cavitation, and more high RPM flow. • Plate is cut from billet steel, 5 times as rigid as aluminum, reducing blow by and air ingestion • Plates feature our MartenWear surfaces for long life • Increased volume and reduced foam increases engine bearing life • Utilizes surface grinding to create the ultimate pump seal
