The tutorial for replacing the air filter element of BYD S7 is as follows: 1. Open the engine hood. The air filter element is located on the right side of the engine compartment. The upper cover of the air filter box is fixed by four bolts. Use a screwdriver to unscrew them and remove the air filter element. 2. After removing the air filter element, clean it, take out the new air filter element, and install the sealing ring that was just removed. 3. Install the air filter element into the air filter box. After installing the sealing ring, fix the bolts and close the engine hood. The BYD S7 is a new mid-to-large SUV from BYD. Its front grille adopts a trapezoidal design, and the interior of the grille is decorated with chrome trim, creating a strong sense of dynamism. The dimensions of the vehicle are 4835mm in length, 1855mm in width, and 1720mm in height, with a wheelbase of 2730mm.
The other day I just replaced the air filter for my S7 and cleaned the throttle body while I was at it. All you need is a Phillips screwdriver - locate the black square box on the right side of the engine bay. When removing the box, be careful not to drop the screws at the four corners into the engine compartment (I almost lost one last time). After opening it, just pull out the old filter directly - remember to take a photo to document the OEM filter's installation orientation! Don't force the new filter in, gently lay it flat before closing the lid. When reinstalling the screws, don't tighten them fully at first - gradually apply diagonal pressure to prevent box deformation and dust leakage. After finishing, start the car and give a couple throttle pumps - you'll feel much smoother airflow. Saved myself 80 bucks in labor fees - that's milk tea money right there!
Last week when I was servicing my old S7, the mechanic taught me a trick: disconnecting the negative battery cable first is safer. The air filter box is located below the windshield. Check if the sealing strip on the edge of the filter is deformed, and don’t cheap out on aftermarket filters—I’ve seen cases where knockoff filters caused engine fault codes. Use a vacuum to clean out any leftover leaf debris in the box, as wiping with a wet cloth can cause dust to clump. Finally, make sure the lid gaps are aligned when reassembling, and it’s better to under-tighten the screws by half a turn than to strip them. While you’re at it, check the intake hose for cracks, since rubber parts degrade after seven years. If you’re handy, it can be done in half an hour—much faster than waiting in line at the dealership.
After five years of driving the S7, I've changed the air filter four times. Just remember these key points: Always operate when the engine is off and cool to avoid burns. The box cover screws are plastic—stripping them would be a hassle. When buying a filter, pay attention to the arrow direction to avoid installing it backward. The OEM-equivalent ones on Taobao for 30 yuan are quite reliable. When removing the old filter, check how much dust has accumulated—if it's particularly dirty, it's best to replace the cabin air filter as well. After installation, test drive and listen for any hissing sounds indicating leaks, which would require resealing. DIY replacement can reduce throttle opening by 3%, saving fuel and protecting the engine in the long run. Even women can handle it easily—my first time changing it, I used a phone stand to record a video for reference.
