VQ35HR/VQ37VHR Billet Pump Cover

The Boundary 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
