Cabin and Engine Air Filters

Both cabin and engine air filters catch debris, dust, and other contaminants to help improve their environments. A cabin air filter is usually found behind the glove box and can be accessed by removing the glove box clips. It catches debris that comes in through the ventilation system. It is recommended to change the cabin filter every 12,000 to 15,000 miles. When you begin to notice persistent odors or low air flow, it may be time for a change.

The engine’s air filter serves the same purpose as the cabin air filter, but it protects the engine from contaminants. Continued road grit can have a harmful effect on parts such as pistons and cylinders. It can eventually cause oil problems and a loss of compression. The engine filter usually sits in its own compartment on top of the engine housing and is easily replaced. Recommendations for replacement average between 20,000 and 30,000 miles.

If you travel a great deal or are regularly in high-dust environments, it’s a good idea to keep an eye on both filters. We’ll be happy to help answer your questions at Faulkner BMW in Lancaster. Schedule an appointment today!
