How to Change Your Air Filter

The car needs air just as much as it needs fuel; although filter is small and inexpensive, but it is one of the most important components in the engine system. Air filters keep the inside of the engine free of dust and insects. Replace or clean your air filter at the recommended interval to keep air flowing freely and your car running its best. Replacing air filters are not complicated, it’s quick and easy, saves your money, and sends your car down the road refreshed and renewed, so you can do this routine maintenance yourself.



  1. Get the correct replacement filter from auto parts store, you may confirm the filter as per OEM No. , you may find the OEM No. on your old filter, the number usually be printed or punched on the filters body. The OE No. just as our ID, the same filter with same OE no., so obtain the correct filter is fist step.
  1. Parking the car on level ground in the shade and apply the parking brake. Shift into first gear (manual transmission) or Park (automatic transmission), and turn off the ignition. Let the engine cool for a few minutes.
  1. While it’s cooling, go get your tools. You’ll need very few for this procedure — grab a butter knife, two medium-sized screwdrivers, one standard and one Phillips, and head back to the car.
  1. Release the bonnet with the lever inside the car. Move the exterior bonnet catch for final release. Lift the bonnet and secure it with the prop rod.
  1. Locate the air filter unit. The air filter unit is usually enclosed in a black plastic casing near the center- top of the engine, It should be the largest non-metal assembly you see.
  1. Remove the air filter Loosen the hose clamp that seals the air conduct. Undo all the screws holding the air filter cover. Some models have wing nuts; other air filters are just clamped on with a quick release system. Keep screws and other parts together and in a safe location so you can find them later. Pull the cover out of the air conduit and lift it up so it comes off the lower part of the housing. Consult a mechanic if you don’t know how to lift the cover.
  2. Take out the air filter. Now you can see a round or panel or cylindrical filter made of nonwoven cloth, paper or gauze. Filters have a rubber gasket that seals off the unit’s interior. Simply lift the filter out of the housing.
  3. Clean the air filter housing. Connect the air hose to the compressor and use the compressed air to blow out the dust, or use a vacuum cleaner to suck up any dirt.
    • Seal the air conduit with removable adhesive tape. It only takes a minute and that way you won’t get any dirt into the engine whilst cleaning.
    • The filters must not getting wet, in case the filter in moist condition, the air flow resistance will increase, and making short working life time, Meanwhile, the filter should be far away oil and fire.
  4. Replace the filter. Replace the old filter with a new one. Simply insert it into the housing with the rubber gasket facing up. Make sure the edges are sealed well by the rubber gasket.
  5. Replace the cover. Carefully insert the cover back into the air conduit and then press the entire piece down onto the lower half of the air filter unit.
    • Make sure it’s on straight and securely; otherwise you could alter engine performance. Tighten all the screws or clamps and recheck that you have put everything firmly back together by rocking the unit gently with both hands. Shut the bonnet securely
  6. Check the filter regularly to keep your car breathing at maximum efficiency by keeping the dust out.
  1. Replacing the air filter every 12 months or 12000 miles ( whichever comes first). If the car usually driving in a dusty area, it will need replacement more often. Your owner’s manual or periodic maintenance guide should have recommendations for your car.
