Oil filters are essential components of an engine's lubrication system in passenger cars and commercial vehicles, found within the Service Parts > Regular Service category. Their primary function is to remove contaminants - such as dirt, metal shavings, and combustion byproducts - from the engine oil, ensuring optimal performance and longevity. Located typically near the engine oil pan, these filters prevent abrasive particles from circulating and causing wear to critical engine components like bearings and pistons. Modern oil filters utilize pleated filter media, often constructed from cellulose or synthetic fibers, to maximize surface area and filtration efficiency. Examples in our range include filters for BMW vehicles, as well as high-quality replacements from MANN Filter (MPN W9507), MAN (MPN 51.05504-0087), Hengst (MPN H11W02), and MAHLE (MPN OX123/1D). Regular oil filter replacement is crucial for maintaining engine health and adhering to vehicle maintenance schedules.
