Now that you have your tools ready, it’s time to start changing your car filter. Here’s a step-by-step guide:

Step 1: Locate the Air Filter Housing

The air filter housing is usually located near the front of the engine, and it is a black plastic box with a large hose running from it. Consult your car’s manual if you’re having trouble locating it.

Step 5: Install the New Air Filter

Insert the new air filter into the housing, making sure it is oriented correctly. Replace the housing cover and secure it with any screws or clips you removed in Step 2.
