Air Filter Restriction Monitoring Gauge
Graduated Indication / Threaded Mount
How it Works
The Filter Minder® Threaded Mount Gauge monitors engine air filters. The position indicator progressively fills the window as air filter restriction increases, locking at the highest restriction. The air filter should be changed when the position indicator reaches the red zone.
The Filter Minder® should be reset whenever the service indicator is checked to determine air filter restriction or when a new air filter is installed. Push the reset button at the end of the service indicator, and the position indicator will return to zero.
