Step 1. Park your car on a flat surface
and open the hood.
Be sure to always have the emergency brake on when working on your car.
Step 2. Bring the correct tools.
First, you'll need to look at your owner's manual to find out what kind of filter your car needs, then purchase one at an auto parts store. You will need a butter knife, a rag, one regular-size Phillips head screwdriver and one regular-size standard screwdriver.
Step 3. Locate the air filter.
Before you start the work, be certain the engine is cool. If it's still hot from driving, let it cool down before you begin. The air filter is generally located in a black plastic case near the top of the engine. It's about the size of a loaf of bread and should be the only plastic case on the top of the engine.
Step 4. Open the case.
This is where the tools may come into play. Generally, the top is held onto the air filter case by metal clips. You can pop open these clips by sliding the butter knife between the clip and the plastic case. Sometimes, the case is held together by screws. If so, use the correct screwdriver and just unscrew the screws.
Step 5. Remove the old filter
and add the new.
Simply lift the old filter out of the case, wipe out any debris in the case with a rag, and place the new filter right side up into the case. Close the top and reattach the clips or screws.
Bring one Phillips head screwdriver, a standard screwdriver, a butter knife, a rag and your new air filter.
Open the case, remove the old air filter and use the rag to wipe any debris from the case.
Place the new filter into the case, close the top and reattach the clips or screws.
