How to replace the air filter on a 1969 AMC AMX?

Replacing the air filter on a 1969 AMC AMX is an essential part of maintaining the vehicle’s engine health. Over time, the air filter can become clogged with dirt and debris, which can restrict airflow to the engine, reducing performance and fuel efficiency. You might notice a decrease in acceleration, a rough idle, or even a drop in fuel economy—these are all signs that your air filter may need replacement. Here is how to solve this issue.

Step 1: Identify the Air Filter Housing
The air filter on your 1969 AMC AMX is housed in a round, metal casing typically located on the top-center of the engine. The housing is a prominent component that sits directly above the carburetor and is usually secured with a wing nut at the top.

Step 2: Remove the Wing Nut
Using your hands, twist the wing nut counterclockwise to loosen and remove it. Set the wing nut aside in a safe place. Once the wing nut is removed, you can lift off the top cover of the air filter housing. This will expose the air filter.

Step 3: Take Out the Old Air Filter
With the top cover removed, you should see the air filter itself. It is a round filter, similar in shape to a large doughnut, and rests in the bottom part of the air filter housing. Carefully lift the old air filter out of the housing. Be mindful of any dirt or debris that might fall off the filter as you remove it.

Step 4: Clean the Air Filter Housing
Before installing the new air filter, take the opportunity to clean out the air filter housing. Use a clean rag or a vacuum cleaner to remove any dust, dirt, or debris that has collected inside the housing. Ensuring a clean environment for the new filter helps to maintain optimal engine performance.

Step 5: Install the New Air Filter
Place the new air filter into the bottom part of the air filter housing. Make sure it sits snugly in place, fully covering the opening of the carburetor. The new filter should fit securely and evenly.

Step 6: Replace the Air Filter Housing Cover
Carefully place the top cover back onto the air filter housing, aligning it properly. Secure the cover by reattaching the wing nut. Twist the wing nut clockwise until it is hand-tight, ensuring the cover is securely fastened.

Step 7: Final Check
After securing the cover, give the air filter housing a gentle shake to ensure everything is tightly in place and there is no movement. Verify that the wing nut is securely fastened and that the air filter housing cover is properly seated.

With the new air filter in place, you should notice an improvement in your 1969 AMC AMX’s performance and fuel efficiency. Regularly checking and replacing the air filter as part of routine maintenance will help keep your engine running smoothly.
