MAHLE Original replacement oil pumps are functionally equivalent to OEM-type specifications for oil flow and pressure. Each one is pre-lubricated and cycle tested with oil to insure that it meets performance requirements. In fact, documented test results show that MAHLE Original oil pumps produce up to 5 PSI more oil pressure than competitive brands under the same operating conditions. Nearly all MAHLE Original oil pumps use cast iron housings to offer better wear life and minimize clearance changes resulting from varying engine-operating temperatures. Cover plates are made of heat-treated, high-grade cast iron. Pump shafts are produced from fatigue resistant, high-strength alloy steel. All of these features contribute to your assurance of a long, trouble-free service life.
