Application

Manufacturer-listed application: Ford/Mazda KLDE 2.5L V6, 1992–1997. The broader KLDE/KLZE description used by distributors does not remove the need to check the exact engine, crank drive and pump configuration.

Match the pump to the installed engine rather than relying on vehicle year alone, especially on engine-swapped cars. No specific vehicle-model or trim fitment is implied beyond the verified engine application.

Installation Planning

Have a qualified engine builder confirm pump compatibility, oil pickup arrangement, clearances and the requirements of the complete lubrication system. Follow Boundary's installation and priming instructions, and verify oil pressure before normal operation.

This listing is for the pump assembly. A pickup, oil pan, external lines or complete engine gasket set is not promised as part of the package. High-flow pump capacity does not correct an unsuitable pickup, oil aeration, poor drainage or incorrect engine clearances.
