How AEM Air Filters Work: Technology and Design
AEM air filters operate on the principle of high-flow filtration. Traditional paper filters use dense fibers to block contaminants, but this can restrict air movement. In contrast, AEM filters employ a layered approach with cotton or synthetic fabric that is lightly oiled. The oil acts as an adhesive, trapping dirt while the open weave of the material permits more air to pass through. This design minimizes pressure drop—the resistance air faces when entering the engine—which is vital for maintaining optimal combustion. The filters are often tested in labs to balance airflow and filtration efficiency, ensuring they meet industry standards. For instance, many AEM filters achieve high filtration rates, capturing over 99% of particulates, similar to OEM filters but with better flow. The construction includes a reinforced rubber or metal frame to prevent collapsing under suction, and the shape is tailored to fit snugly in air intake boxes or aftermarket cold air intake systems. This attention to detail ensures consistent performance across different driving conditions, from city commuting to off-road adventures.
Installation Process for AEM Air Filters
Installing an AEM air filter is generally straightforward and can be done at home with basic tools. First, ensure you have the correct filter model for your vehicle by checking the manufacturer’s website or packaging. Start by disconnecting the battery to prevent any electrical issues. Locate the air filter housing in your engine bay—it’s usually a plastic box near the engine with clips or screws. Open the housing and remove the old filter, noting its orientation. Clean the housing with a damp cloth to remove any debris. Then, insert the AEM filter, making sure it sits flush and seals properly to avoid unfiltered air leaks. Secure the housing and reconnect the battery. For vehicles with mass airflow sensors, avoid touching the sensor during installation. After installation, start the engine and listen for unusual sounds; a proper fit should result in smoother idling. If you’re upgrading to a full cold air intake system that includes an AEM filter, follow the provided instructions carefully, as this may involve more steps like relocating components. Always refer to your vehicle’s manual for specific guidance to avoid voiding warranties.
Maintenance and Cleaning of AEM Air Filters
Regular maintenance is essential to keep an AEM air filter performing optimally. Unlike disposable filters, AEM filters require cleaning every 30,000 to 50,000 miles, or more often in dusty environments. Start by removing the filter from the housing. Use a soft brush to gently remove loose dirt. Then, apply a dedicated air filter cleaner—AEM offers its own brand—spraying it evenly and letting it soak for 10-15 minutes. Rinse with low-pressure water from the inside out to push dirt away from the filtering media; avoid high-pressure water as it can damage the fibers. After rinsing, shake off excess water and let the filter air dry completely; never use heat sources like hair dryers, as they can warp the material. Once dry, re-oil the filter with AEM-specific filter oil, applying it lightly and evenly. Too much oil can restrict airflow, while too little reduces filtration. Allow the oil to soak for 20 minutes before reinstalling. This process restores the filter’s efficiency and ensures long-term durability. Keep a maintenance log to track cleaning intervals, and inspect the filter periodically for tears or excessive clogging.
