Melling M452HV-386S High Volume Oil Pump with Screen 5.7L HEMI

The Melling M452HV-386S is a high volume replacement oil pump with pickup screen engineered for 5.7L HEMI engines. Designed to deliver superior engine lubrication over the stock pump, this assembly provides increased oil flow for improved idle pressure and enhanced protection under demanding operating conditions.

Melling's high volume design increases oil flow by an average of 12% over the OEM pump, helping maintain consistent pressure at idle and throughout the RPM range. The pump features a hard coat anodized aluminum housing with a phosphate-coated cast iron cover for durability and corrosion resistance. High volume gears are machined to close tolerances to ensure proper pressure and efficient operation, while precision ground end plates deliver maximum wear resistance.
