3 Answers
Method for replacing the air filter in a BMW 5 Series: 1. Open the engine hood and locate the air filter. 2. Unclip the two fasteners holding the cover, then lift the entire air filter cover. 3. Remove the old air filter from the opened cover. 4. Install the new air filter, replace the cover, and secure the fasteners. Taking the BMW 5 Series 2021 525Li Luxury Package as an example: It is a mid-to-large-sized sedan introduced by BMW Brilliance, with dimensions of 5106mm in length, 1868mm in width, and 1500mm in height, and a wheelbase of 3105mm. It is equipped with a 2.0T turbocharged engine, delivering a maximum power of 135kw, paired with an 8-speed automatic transmission.
Last time I changed the air filter on my BMW 5 Series, the whole process was actually quite simple. After opening the hood, I located the black air filter housing right next to the battery, secured with clips or screws. I released the clips by hand, lifted the housing cover, and pulled out the old filter - it was completely covered in dust and grime. Before inserting the new filter, I checked the arrow direction to ensure proper installation and prevent reverse airflow. When closing the cover, I pressed firmly to seat the sealing gasket properly. I make it a habit to replace it every 1-2 years to keep the engine breathing smoothly, ensuring better acceleration, improved fuel efficiency, and extended engine life. All you need is a Phillips screwdriver, but if you're not inclined to DIY, you can always buy compatible filters at auto parts stores - no need to overspend.
When replacing the air filter for my BMW 5 Series, I started from scratch. After opening the hood, I let the car cool down for a few minutes—safety first. The filter box is usually located near the front by the fan, secured with a plastic casing. I gently released the clips or screws by hand to remove the cover, took out the old filter, and cleaned the dust inside the box to prevent impurities from mixing in. When installing the new filter, I made sure not to bend or deform it, aligning it properly with the slots. A clicking sound confirmed it was locked in place when I put the cover back on. This DIY job saved me a trip to the shop. I recommend using genuine BMW or reputable brand filters to prevent engine efficiency loss and increased fuel consumption. Regular replacement helps maintain clean and comfortable air inside the car.
