Product Description

The **Boundary CM-S1-R2-BBP** is a high-performance oil pump made for the newer Ford Coyote V8 (5.0 L) - specifically for 2018+ Mustangs and F-150s. Starting from the OEM housing, this pump is upgraded with billet chromoly internal gears and a rigid billet back plate (BBP) to handle high RPMs and increased oil demand.

During assembly, every component is carefully cleaned, deburred, and inspected. Fasteners are upgraded to stainless Torx, sealed with Loctite, and critical areas are treated with anaerobic sealant to minimize cavitation and ensure quick oil delivery on startup. This pump offers improved oil flow and pressure under demanding conditions - making it ideal for performance builds, tuned or high-revving Coyote engines.
