This is my go-to oil filter for BMW oil changes. You really can’t go wrong with this brand—they’re made from good-quality materials and have been very consistent from one oil change to the next. Fit and performance have always been exactly what I expect. The included crush washer is an appreciated addition so that I don't need to create a separate order. Installation is a breeze as it simply slides in. The gasket for the oil filter housing appears to be made well and is also east to install. The only thing I wish is that the filter came with the O-rings for the piece that holds the filter in place inside the housing. Other than that minor detail, this is a reliable, high-quality filter that I’ll continue to use.

From the moment I unboxed it, the quality of this filter was evident. Mann Filter is renowned for its OEM-level (Original Equipment Manufacturer) quality, and the HU925/4X is no exception. The construction is robust, and the filter media feels dense and durable, clearly designed to capture even the finest contaminants effectively. Installation is straightforward for anyone familiar with their vehicle's oil filter location. It fits perfectly, ensuring a tight seal and preventing any leaks. What truly matters, however, is its performance between oil changes. I've noticed that my engine oil stays cleaner for longer, which speaks volumes about the filter's ability to trap impurities and protect vital engine components. Using a high-quality filter like the Mann HU925/4X is a small investment that can save you significant money and headaches down the road by extending engine life and maintaining optimal performance. It's a critical component in keeping your engine running smoothly and efficiently.

Mann is the OEM supplier for BMW and makes the best paper filters anywhere. I have trusted them for years and you should, too.
