One Stop Purchase Oil Pump 11277594471 for BMW N46

This oil pump OE 11277594471 is a vital lubrication component specially designed for BMW N46 engine. Driven by the engine crankshaft, it pressurizes and circulates engine oil throughout the whole lubrication system, delivering sufficient oil to crankshaft bearings, camshafts, pistons and other moving friction parts. Continuous oil supply forms protective oil film between metal contact surfaces to reduce friction and wear, while taking away heat and metal debris generated during engine operation. Manufactured with high-strength cast housing and precision machined internal rotors, this oil pump features stable oil pressure output, low noise and outstanding wear resistance. It can maintain consistent oil supply under variable engine speed and load conditions. Each oil pump passes strict oil pressure test and leakage inspection before leaving factory to guarantee reliable performance. A faulty oil pump will result in insufficient oil supply and low oil pressure warning. Without timely repair, engine components will suffer severe dry friction, leading to scuffing, locking and permanent engine damage. This high-quality aftermarket oil pump matches original installation dimensions perfectly for direct replacement. It rebuilds normal lubrication circulation, stabilizes working oil pressure and effectively protects internal engine parts, serving as a reliable spare part for BMW N46 engine overhaul and daily maintenance.
