BMW M4 cabin air filter is located under the wiper on the passenger side. To replace the cabin air filter, you need to open the hood. When driving with the air conditioning on, the car draws in outside air into the cabin, but this air contains various particles such as dust, pollen, soot, abrasive particles, ozone, odors, nitrogen oxides, sulfur dioxide, carbon dioxide, benzene, etc. Without the cabin air filter, these particles would enter the cabin, not only contaminating the car's air conditioning system and reducing cooling performance but also causing allergic reactions, lung damage, irritability from ozone exposure, and unpleasant odors - all of which affect driving safety. The replacement interval for BMW M4 cabin air filter depends on usage conditions. For typical urban family cars, it's recommended to replace it every six months or once a year.

As a seasoned driver with over 20 years of experience, I can tell you that the BMW M4's cabin air filter is located behind the glove compartment on the passenger side. To replace it, you'll first need to remove the glove box, which is quite simple: empty the contents, unscrew the screws on both sides or push the clips, and the entire box can be taken off, revealing the filter compartment. The location is designed for easy maintenance, and doing it yourself saves both money and time. I recommend checking it every six months or 10,000 kilometers to ensure high filtration efficiency and prevent dust from clogging the air conditioning system. Choosing an original equipment manufacturer (OEM) filter can extend its lifespan and also prevent unpleasant odors from affecting respiratory health. If your usual parking environment is dusty, you should replace it more frequently, ensuring comfort and peace of mind on long trips without worrying about allergy issues.

As a BMW M4 owner, I just replaced the cabin air filter last year, which is located inside the glove compartment on the passenger side. Finding its position is quite simple: sit in the car, open the glove box, and you'll see a small door at the bottom of the inner wall - that's the filter housing. When replacing it, I recommend keeping a small wrench or screwdriver handy. Just gently remove the old filter and insert the new one - make sure to follow the arrow direction to avoid incorrect installation. I learned how to do it by watching online video tutorials, and the whole process only takes a few minutes, saving me hundreds in repair costs. Regular ventilation while driving helps extend the filter's lifespan and keeps the cabin air fresh and comfortable.

As a car enthusiast, I know that the cabin air filter in the BMW M4 is located behind the glove box, making it easy for DIY. During maintenance, simply unclip the glove box to access and replace the filter, which traps dust and pollen to protect the AC system's efficiency. The replacement frequency varies with usage—changing it every 15,000 km for suburban driving is ideal to prevent system clogging.
