AEM Synthetic Air Filter Cleaner is a specialized solution engineered to restore the flow efficiency of non-oiled synthetic air filters. Formulated to penetrate deep into filter media, it loosens and dissolves accumulated road grime, dust, and debris so they can be safely rinsed away with water.

This cleaner is specifically designed for the maintenance of AEM Dryflow air filters and is compatible with most other high-performance synthetic filters. Because these filters do not require oiling, this cleaning solution is the primary tool needed to maintain optimal filtration and airflow throughout the life of the component.

• Part Type: Synthetic Air Filter Cleaner
• Container Size: 32oz
• Compatibility: AEM Dryflow and other non-oiled synthetic media filters
• Application: Spray-on cleaner for water-rinse maintenance
• Formulated to dissolve heavy dirt and grime buildup

Custom intake systems and larger-diameter piping often introduce air turbulence that disrupts Mass Air Flow (MAF) sensor accuracy. The AEM Air Straightener is engineered to solve this by converting chaotic, turbulent air into a smooth, laminar flow before it reaches the sensor. By smoothing the air column, this insert ensures the MAF sensor receives a consistent and accurate reading, which is critical for precise ECU fueling calculations.

• Eliminates MAF signal "noise" for more stable idle and improved part-throttle driveability
• Honeycomb grid design provides minimal airflow restriction while maximizing straightening efficiency
• Essential for custom intake builds and larger-than-stock intake tube diameters where factory flow characteristics have changed
• Promotes accurate fuel trims and more predictable engine tuning
