What are the OEM brands for BMW's three filters?
3 Answers
The three filters in a car refer to: the fuel filter, air filter, and oil filter. The OEM brands for BMW's three filters are as follows: oil filter: Mann-Filter, air filter: Mahle, fuel filter: Mann-Filter. Additionally, the OEM brand for BMW's cabin air filter is also Mann-Filter. The functions of the three filters are as follows: Air filter: The air filter (AirFilter) is mainly used in pneumatic machinery, internal combustion machinery, and other fields. Its function is to provide clean air for these mechanical equipment to prevent them from inhaling air containing impurities and particles during operation, thereby reducing the likelihood of wear and damage. Fuel filter: The main function of the fuel filter is to filter out impurities in the gasoline. Oil filter: The oil filter, also known as the oil element, is used to remove impurities such as dust, metal particles, carbon deposits, and soot particles from the oil to protect the engine. The oil filter should have the characteristics of strong filtration capability, low flow resistance, and long service life.
I've been driving a BMW for several years. The main OEM filter brands for BMW are Mann-Filter and Mahle. These two manufacturers often supply oil filters, air filters, and cabin air filters. The quality of OEM filters is exceptionally high, with strong filtration efficiency that effectively protects the engine from wear caused by impurities and extends the lifespan of air filters. I've tried aftermarket brands before—they're cheaper, but problems arise quickly. Dust entering the engine leads to reduced performance, and repairs end up being troublesome and costly. For maintenance, it's recommended to check every 10,000–20,000 km. Replacing the cabin air filter before summer improves in-cabin air quality. Although OEM parts are more expensive, they're safer and save money in the long run. BMW's official maintenance manual clearly labels the OEM manufacturers, and you can also verify authenticity online to ensure genuine parts.
When maintaining my BMW, I always prioritize genuine OEM filters. BMW typically sources them from Mann or Bosch, with the oil filter and air filter being particularly reliable. The advantage of OEM parts lies in their perfect compatibility with the vehicle design, high filter density, and their ability to reduce exhaust emissions and engine noise. I once tried saving money with aftermarket brands, such as an air conditioning filter that wasn't durable, resulting in poor cooling and strong odors in the summer, which wasn't worth it. Generally, they should be replaced every maintenance cycle, as a dirty air filter can affect fuel efficiency. It's advisable to follow the manufacturer's manual. Additionally, purchasing genuine parts from 4S stores or authorized dealers is more reassuring to avoid counterfeits. Sticking to OEM maintenance can prevent major repairs and save money in the long run.
