In the past we’ve had to rely on our eyeballs or some manufacturer’s recommendation to determine when an air filter should be serviced. Now there’s a more accurate way. The AEM Filter Minder Gauge constantly monitors airflow and its gradual decrease as an air filter becomes dirty. The air filter does its job by preventing dirt and debris from entering and damaging your engine. But as it does, the dirt and debris begins to collect on the filter, restricting airflow. The AEM Filter Minder senses this restriction, and displays the condition of the filter on the gauge. The needle will stay in the green zone when there is very little restriction and the air filter is clean. As time goes by and restriction increases, the needle will move into the yellow zone. When the needle reaches the red zone, it’s time to clean your filter and reset the gauge. Filter Minder Gauges can be installed inside the cabin or under the hood. Simply tap into the vacuum source on the lid of the air filter and connect the vacuum hose to the back of the gauge. All hardware and complete instructions are included.
John Concialdi and Bob Sullivan co founded AEM in 1987 as a tuning performance shop in Compton California. Both men had extensive technical backgrounds in engines and engine airflow, and in a short time AEM became the go-to company for performance modifications. By 1993, when the company relocated to Gardena California, it had become commonplace to see cars wearing the bright yellow AEM logo winning races. AEM tirelessly dyno tested and worked closely with racers and auto manufacturers in an effort to understand intake energy dynamics. This resulted in the sale of their first air intake kit in 1994. AEM can boast a number of firsts and unique products: They’re the first manufacturer to make an intake system with specific tube lengths and diameters to take advantage of pressure waves in the inlet tract; they developed the first dual chamber intake kit; they designed an air bypass valve to prevent hydro-lock should the air filter ingest water; and they created one of the first hybrid intake systems for modified cars. AEM continues to create innovative products to help you get more power from your car.
