Replacing the air filter on your Briggs and Stratton engine is a relatively simple process that can help improve its performance and extend its lifespan. A dirty or clogged air filter can reduce engine power, increase emissions, and even cause the engine to stall or refuse to start. In this article, we'll walk you through the process of replacing the air filter on your Briggs and Stratton engine, including the tools and materials you'll need and some tips for maintaining your engine.
The Importance of Air Filter Maintenance
Air filter maintenance is an essential part of engine maintenance, and it's something that you should do regularly to ensure your engine is running at its best. When the air filter becomes clogged with dirt, dust, and other debris, it can reduce airflow to the engine, which can lead to a range of problems, including:
- Reduced engine power and performance
- Increased emissions and pollution
- Engine stalling or refusal to start
- Overheating and engine damage
Tools and Materials Needed
To replace the air filter on your Briggs and Stratton engine, you'll need the following tools and materials:

- Replacement air filter (specific to your engine model)
- Socket wrench or ratchet and socket
- Air filter wrench (optional)
- Soft cloth or brush for cleaning
Step 1: Locate the Air Filter
The air filter on your Briggs and Stratton engine is usually located on the side of the engine or on the carburetor. Consult your owner's manual or engine manual to determine the exact location of the air filter on your specific engine.
Step 2: Remove the Air Filter Housing
Once you've located the air filter, you'll need to remove the air filter housing to access the filter. This may involve removing screws or clips that hold the housing in place. Use a socket wrench or ratchet and socket to remove any screws, and be careful not to damage the housing or any surrounding components.
Step 3: Remove the Old Air Filter
With the air filter housing removed, you should be able to access the old air filter. Use your hands or a soft brush to gently remove any debris or dirt from the filter. Be careful not to touch the filter's internal surfaces, as this can cause damage.

Step 4: Inspect and Clean the Air Filter Housing
Take a moment to inspect the air filter housing and clean it with a soft cloth or brush. Remove any dirt, dust, or debris that may have accumulated, and make sure the housing is free of any obstructions.
Step 5: Install the New Air Filter
With the air filter housing clean and the old filter removed, it's time to install the new air filter. Place the new filter in the housing, making sure it's properly seated and any gaskets or seals are in place.
Step 6: Reassemble the Air Filter Housing
Once the new air filter is in place, reassemble the air filter housing by replacing any screws or clips you removed earlier. Make sure everything is securely fastened and the housing is properly sealed.
