Editor's Pick: Changing an air filter is something you can easily do yourself, no need to make a special trip to the repair shop. Open the hood, find the filter box, loosen a few clips, pull out the old one, drop the new one in facing the same direction, and snap it back closed — the whole thing takes just a few minutes. The filter media offers generous surface area to keep the intake clean, so your engine breathes easy and throttle response feels a bit lighter too. Check it roughly every 12,000 miles (20,000 km); in dusty areas, change it more often.
