In any vehicle (not electric obviously), air plays a role just as important as the fuel. The air entering the engine passes through the air filter so that it is free from any foreign particles. This is very important as any impurities inside the engine can cause trouble in the ignition process. Not only that but impurities would increase the wear of the engine and cause trouble in smooth operation. That is why all the vehicles have air filters so that the engine doesn’t have to take the hit and the air entering the engine is absolutely clean and free from any foreign particles. But with time, the air filter tends to accumulate lot of dirt which affects the performance and efficiency of the vehicle. So it is important to clean the air filter frequently and replace it at specific intervals. Here is how to replace the air filter in your car.

Find the replacement
To replace the air filter in your car, the first thing you need to do is find a replacement. If you are not familiar with the kind of air filter that your car uses, consult the user manual or maybe consult the guy form the auto parts store. It is quite possible that there are different air filters available for your car model. This is because many models have been around for ages and there have been different generations of the same model that vary largely. In such cases, the air filters are also very different along with the other components. Make sure the one you are picking is right for your particular model. The filters might also vary with different engine specifications so keep that in mind as well. Air filters are really inexpensive and so the price difference between different models won’t be huge either.

Secure your car
Park the car properly on level surface and turn off the ignition. Put the park brake in and leave the car in gear for manual vehicles. Now find the switch for releasing the hood. This is mostly found below the dashboard and in case you are unable to find it, consult the user manual. Open the bonnet using the exterior bonnet release and secure it in its place with the prop rod.

Locate the old filter


Locate the air filter box inside the bonnet. Usually it is a square or rectangular plastic box in front of the car slightly off from the center. The box is usually located near the top for easy access. This box contains the air filter. See how the box is closed. Some of them use just clamps for a quick release while others use multiple screws. You will find a hose connecting to the air filter box. This hose is secured in its place by a hose clamp. Loosen this clamp a bit to allow for the removal. Now remove the screws of the air filter housing so that the top half can be removed. Put the screws safely in a tray so that they can be easily found later. Remove the top half from its place to reveal the air filter.

Removing and cleaning


The air filter can be made out of different materials like cotton, paper or foam. The periphery would be made out of rubber so that the air cannot escape into the passage without passing through the air filter. Just hold the air filter from the rubber edges and pull it out of its housing. After this clean the air filter housing properly. This is important as some dirt tends to accumulate in the housing after long usage. You can use a vacuum cleaner on its blower end to blow out all the dirt from the housing. While doing this, make sure you seal the air conduit using self-adhesive tape. This would prevent the dirt from making it to the engine while cleaning.

Replace the filter


Put the new air filter in the old filter’s place. Make sure the rubber rim around the filter is facing upwards. Also ensure that the edges of filter housing are sealed properly by the rubber rim and there is no gap for the air to escape. Put the cover back in place properly. Make sure it sits flat on the housing and all the points match the original. Put the clamp/ screws back in place and make sure it is fixed firmly. Slide back the hose in place and tighten its clamp. Close the bonnet and you are done.
