The ECOGARD X10002 Oil Filter is engineered to provide exceptional engine protection for BMW 550i xDrive 4.4L models from 2011 to 2016. Designed to meet OEM specifications, this filter ensures optimal fit, form, and function, contributing to the longevity and performance of your engine. Its high-efficiency media captures over 97% of contaminants as small as 30 microns, safeguarding critical engine components from abrasive particles. The one-piece spiral wound, corrugated center tube enhances collapse strength, maintaining filter integrity under high-pressure conditions. A molded nitrile anti-drain back valve prevents dry starts by retaining oil within the filter when the engine is off, while the pressure relief valve ensures continuous engine lubrication, even during cold starts. The heavy-duty filter body withstands five times the normal oil pressure, and the precision-forged baseplate threads provide a secure seal, reducing the risk of leaks. Compatible with various BMW models, including the 550i xDrive, 650i, and M5, the ECOGARD X10002 Oil Filter offers a reliable and cost-effective solution for maintaining engine health and performance.
