How Does It Work?

The graduated indicator 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.

Mounting

Mounts in a rubber grommet directly to air cleaner housing or air induction piping. Rubber grommet available.
