Champion air filters are your engine’s first line of defense, providing superior protection against damaging contaminants entering the combustion system. All Champion filters use activated carbon and feature an optimized pleat count, making them up to 99% efficient at eliminating exhaust and other foul odors and ensuring maximum performance without restricted air flow. We recommend replacing your filters every 12 months or 12,000 miles to maintain peak performance.


Ready to breathe like a Champion? It’s a relatively easy job to install a replacement filter. Here are the step-by-step instructions.

Step 1
Open your car’s hood and find the engine air filter housing. It’s a black plastic box that sits on top of or to the side of the engine. You will see a large hose sticking out of its side.


Step 2
Open the air filter housing and take out the old air filter (use caution when removing the housing cover as it may have wiring harness and electrical components attached to it). The air filter housing can be fastened together with screws, clips, clamps or wing nuts. Take note of what kind of fasteners are used and select the appropriate tool to remove them. To open the air filter housing, you simply remove the fasteners, remove the top of the air filter housing and take out the air filter. Remove any dirt or debris that is in the housing by wiping it out with a rag.


Step 3
Inspect the old engine air filter to make sure that it is dirty and needs changing. Look inside the pleats, if you see a lot of dirt, it is time to change the air filter. You can also tap the filter and if dirt falls out, your air filter is past its prime and needs replacing.

Step 4
Place the new engine air filter in the filter box. Insert it with the rubber rim facing up. Ensure that it is seated correctly.


Step 5
Put the top of the housing back on and put the fasteners back on. That’s it! You have replaced your air filter and saved a bunch money by doing the job yourself.
