What You'll Learn

Removing the filter
Removing the AEM air filter is a simple process, but it requires careful handling. First, you need to remove the air filter from the intake pipe, OE airbox, or custom assembly. Loosen any clips or clamps holding the air filter in place, and gently lift it out. Be cautious not to damage the surrounding components or the filter itself. Once removed, lightly tap the filter to remove any loose dirt and debris. This initial step will make the subsequent cleaning process more effective.
It is important to note that different vehicles may have unique designs and configurations for their air filters. While the basic principles of removal and cleaning remain consistent, you should consult specific instructions for your vehicle make and model if available. This ensures that you can safely and effectively remove and clean your AEM air filter.
After removing the filter, it is essential to handle it with care. Avoid touching the inner surfaces of the filter, as this can affect its performance. Hold the filter by its edges or frame whenever possible. Additionally, pay attention to the filter's orientation during removal, as it should be reinstalled in the same direction. Marking the filter and its housing with arrows or other indicators can help ensure proper alignment during reinstallation.
Some AEM air filters may have specific recommendations or requirements for removal. For example, certain filters may suggest using a flat-head screwdriver to loosen the intake hose and release the clips holding the airbox together. Always refer to the instructions provided by the manufacturer or consult a trusted source for specific guidelines related to your particular AEM air filter.
Once the filter is successfully removed, you can proceed with the subsequent steps of cleaning and maintenance, ensuring that your AEM air filter performs optimally and extends its lifespan.

Applying the cleaning solution
When it comes to applying the cleaning solution to your AEM fuel filter, there are a few methods you can use. The first method involves using the AEM cleaning kit, which includes a cleaning solution specifically designed for AEM filters. This method is as follows:
- Remove the filter from the intake pipe, OE airbox, or custom assembly.
- Tap off all loose dirt and debris.
- Measure the length of the filter media and fill a bucket with warm water to that depth.
- Add one 12-ounce bottle of the AEM Filter cleaning solution to the water.
- Submerge the filter in the solution for 10 minutes, ensuring the solution doesn't flow into the filter neck.
- Remove the filter, rotate it back and forth to agitate the water, and knock off any remaining dirt.
- Empty the bucket and repeat the previous two steps with a new batch of cleaning solution.
- Rinse the filter with clean water, rotating it to ensure all dirt is removed.
Another method for applying the cleaning solution is to use a mild, multi-purpose cleaner such as Simple Green or a grease-cutting soap like Dawn. Here is a general outline of this method:
- Remove the filter and tap off loose dirt and debris.
- Liberally spray the cleaner onto both sides of the filter, focusing on the dirtier side.
- Allow the cleaner to soak into the filter for 10 minutes.
- Rinse the filter with cool or warm water, ensuring you rinse from the clean side out to flush out dirt and debris.
- Repeat the previous two steps until the water flowing through the filter is completely clear.
It is important to note that AEM filters do not require oiling, so be sure to avoid any solutions that may contain oil. Additionally, always allow the filter to air dry naturally or use compressed air to speed up the process. Do not use heat or an open flame to dry the filter.

Rinsing the filter
Firstly, it is important to note that the rinsing process should be done with cool or warm water, not hot water. Start by directing the water flow from the clean side of the filter, which is the side closer to the throttle body, and work your way outwards. This ensures that the water pushes the dirt and debris out of the filter, preventing it from getting pushed deeper into the filter media. You can use your fingers on the hose to apply light water pressure if needed.
If you are using a bucket to soak and rinse the filter, ensure that you completely empty and refill the bucket with clean water between soaks. Repeat the process of soaking and rinsing until the water flowing through the filter media is completely clear of any dirt or debris. This may take several repetitions, so be patient and thorough.
When rinsing, avoid using high-pressure water, as this could damage the filter media. Instead, opt for a gentle flow of water, and use your hands to agitate the water and help remove any stubborn dirt particles.
After you have thoroughly rinsed the filter, gently shake off any excess water. It is important that you do not wring or squeeze the filter, as this could damage the filter media and affect its performance. Allow the filter to air dry naturally, or you can carefully use compressed air to speed up the drying process.
It is important to note that AEM filters do not require oiling, so make sure you do not apply any oil to the filter after rinsing and drying.

Drying the filter
If you are in a hurry, you could try setting the filter out for about 24 hours, and it should be dry. Alternatively, you can shake the filter dry by pulling it out of the cleaning solution and shaking off any excess liquid. However, it is important to ensure that the filter is completely dry before remounting it.
Another option is to use a mild, multi-purpose cleaner, such as Simple Green, to help speed up the drying process. Spray the cleaner on both sides of the filter element and then rinse with cool or warm water. Repeat these steps until the water flowing through the filter is clear of any dirt or debris.
It is worth noting that some sources recommend using oil after cleaning and drying the filter. This helps guard against corrosion and aids in dirt entrapment. However, it is important to note that AEM filters do not require oiling, and you should not oil the filter if it is a Dryflow filter.

Reinstalling the filter
If you are reinstalling an AEM Dryflow filter, it is important to note that these filters do not require oiling. Do not apply any oil to the filter media, as it may damage the filter or affect its performance.
For AEM V2 filters, the process is similar. Remove the old filter by undoing the strap that holds it in place, then install the new filter and secure it with the strap. Ensure that the filter is properly aligned and seated correctly in the airbox or intake pipe.
After reinstalling the filter, it is a good idea to inspect your work and ensure that the filter is secure and properly installed. Check for any loose dirt or debris that may have fallen into the airbox or intake pipe during the process, and remove it if necessary. Finally, close any panels or covers that you may have removed to access the filter.
By following these steps, you can ensure that your AEM fuel filter is properly reinstalled and ready for use.
