3 Answers
First, remove the glove box by sitting in the passenger seat and pressing both sides of the glove box firmly with both hands. The material of the glove box is relatively soft. After removing the glove box, you can see the Mazda 6's cabin air filter. Take it out for replacement. Unpack the new Mazda 6 cabin air filter you purchased, paying attention to the installation direction. The new cabin air filter should have markings indicating which side should face up.
As a DIY enthusiast, I've always enjoyed replacing my car's air filter myself because it's super easy and saves money. In my Mazda, the air filter box is located at the front of the engine compartment, near the windshield washer fluid reservoir, typically a black plastic box. The cover is secured with hand-tightened screws or clips, requiring no additional tools—just a gentle twist or press to open. Remember to do this when the engine is cold to avoid burns. After removing the old filter, I clean the inside of the box with a damp cloth to remove dust, then install the new filter—paying special attention to the arrow direction, which must point toward the engine's airflow direction; otherwise, it will affect filtration efficiency. Once the new filter is in place, close the cover and tighten the screws or press the clips back. The whole process takes just 5 minutes. I recommend replacing it every 20,000 km, or sooner if you drive in dusty areas. Buying the filter yourself is very affordable—around 50 yuan for OEM or just 20 yuan for aftermarket—saving over 100 yuan in maintenance fees. Plus, it improves engine performance, makes the car run smoother, and reduces fuel consumption. DIY also allows you to inspect other components, but be careful not to touch wires or fuel lines—just wear gloves for hand protection. There's no risk involved, and after trying it once, you'll love it.
When replacing the Mazda air filter, I always prioritize safety because improper operation may allow dust to enter the engine. First, ensure the engine is not running and has cooled down before opening the hood. Locate the air filter housing—on most Mazda models, it's positioned on the right side of the engine bay near the windshield wipers. The housing cover usually features clips or plastic screws and can be gently loosened by hand—avoid using excessive force to prevent damage. After opening, slowly remove the old filter to prevent debris from falling into the intake. Before installing the new filter, check that the rubber seal is intact and align it correctly—the arrow always points toward the rear of the vehicle, indicating the airflow direction. Press the cover firmly after closing to test the seal. DIY replacement takes less than 10 minutes, saving money efficiently, but be mindful of cleanliness to avoid introducing contaminants; wear gloves to prevent slipping from oily hands. Opt for branded filters to prevent air leaks—online purchases cost between 20 to 50 RMB, cutting expenses by half compared to repair shops. Regular replacement (every 10,000–20,000 km) helps prevent increased fuel consumption and extends engine life. If unsure, seek assistance or watch video tutorials—safety first, don't take risks.
