Repair Summary
This article covers replacing the engine air filter in a BMW F39 X2 vehicle with the B46 turbocharged 4 cylinder engine. Even though we used a 2018 X2 to perform this repair, this article can be applied to any 2014+ X1, X2 or MINI (including the Clubman and Countryman) vehicle with minor modifications.

A BMW X2 air filter replacement takes less than 15 minutes and can save you an expensive trip to the dealership.

One of the easiest maintenance items you can perform on your BMW X2 SAV is replacing the engine’s air filter. But don’t underestimate the importance of this simple service procedure; your BMW X2 air filter plays a very important part in the longevity and performance of your X2’s engine. It plays a pivotal role in the health of your engine by filtering out dirt, sand and other air borne contaminates that can become trapped inside the motor causing damage to many of its internal parts. Performing a BMW X2 air filter replacement on a regular basis is as important as changing your engine oil…not doing so can severely shorten the lifespan of your engine.

According to the BMW X2 owners manual, the air filter should be changed every 5th oil change, or approximately 50,000 miles. The BMW Repair Guide disagrees with the BMW factory recommendation…we strongly suggest that all X2 owners change their engine air filter every 10,000 miles or once a year (whichever occurs first). If you drive for an extended period of time in highly contaminated conditions (dirt roads, road construction, etc.) you will need to perform a BMW X2 air filter replacement even more frequently.

Replacing the air filter on your X2 costs less than $20 and can be done in 15 minutes by even the most novice of home mechanics. Save yourself an expensive trip to the dealership by doing your own BMW X2 air filter replacement. We provide you with a list of high quality replacement air filters below that can be delivered to your door in just a couple of days.

The Level of Difficulty displays graphically how challenging the repair is, from beginner to expert. Beginner repairs usually require very few tools, have short repair times and are simple to complete for even the most novice of mechanics. As the difficulty level rises expect the repair to demand more time, use more specialized tools, and require a better understanding of mechanics to complete the job.

The Repair Cost graphically displays approximately how expensive the repair will be to perform. The repair cost is defined as the actual money that would need to be spent to purchase required parts and special tools that would not be normally found in the home mechanics garage. Please note that these cost estimates are approximate and can fluctuate based on brand preferences and manufacturer.
