Last time I changed the air filter for my 730, it was super easy—just needed a Phillips screwdriver. First, pop open the front hood and locate the black plastic square box on the left side of the engine. Use the screwdriver to loosen the screws at the four corners of the box cover, being careful not to let the screws fall inside. Open the cover and you’ll see the old filter—just pull it out. Before placing the new filter, remember to blow out any dust inside the filter box, or the replacement will be pointless. When installing the new filter, pay attention to the arrow mark on the side—it should point toward the engine. Don’t overtighten the screws when sealing the cover back, as the plastic box can easily strip. The whole process takes about 20 minutes, saving you unnecessary repair shop costs. It’s recommended to replace the filter every 20,000 km—otherwise, restricted airflow can make the engine less fuel-efficient. Buying the part yourself costs just over 30 bucks, and you’ll feel the throttle response improve afterward.
When it comes to replacing the air filter for the 730, here's a little tip. When removing the screws from the filter housing, use a magnetic screwdriver first to prevent the screws from falling into the engine bay and getting lost. After taking out the old filter, carefully inspect the corners of the housing. Last time, I found a pile of leaves stuck in the sealant gap. Don't force the new filter in; align it with the housing slots and push it gently into place. Installing the air filter upside down is a no-go—make sure the triangular mark on the filter edge points toward the front of the car. If you're not very handy, it's a good idea to have a small vacuum ready to clean the filter compartment. After the replacement, start the engine and listen—if the sound is muffled, you should check if it was installed incorrectly. By the way, in northern areas with heavy dust and sand, it's best to open and inspect the filter every 5,000 kilometers, as it gets dirty quickly and can affect the air conditioning airflow.
