Air Filter Restriction Monitoring Gauge / Switch
Graduated / Electrical Indication / Threaded Mount
How It Works
A combination graduated indicator and switch, the Filter Minder® Graduated Switch features a position indicator that progressively fills the window as air filter restriction increases, locking at the highest restriction. When it reaches the red zone, or highest recommended restriction, it sends a signal to the filter warning light on the dash or to the engine computer to record as a diagnostics fault. The warning light locks on until the indicator is reset.
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.
