AEM Filter Minder® Gauges

AEM Filter Minder^® gauges help indicate when your AEM air filter needs cleaning
With AEM's new line of Filter Minder gauges, the guesswork has been eliminated. Knowing when it is time to service your air filter has never been easier. AEM Filter Minder gauges constantly monitor air filter restriction.

When an air filter becomes dirty it holds much of the dirt and debris that was kept from entering your engine. With dirt and debris in the air filter it becomes restricted and unable to flow as well. The Filter Minder gauge senses this restriction and displays the current condition of your air filter on the gauge. When the air filter is clean with little restriction, the needle will stay in the green portion of the gauge. As the air filter moves through its service life you will see it move into the yellow portion. Once the Filter Minder needle reaches the red zone it is time to clean your air filter and reset the Filter Minder gauge.
