A Filter Minder® works as air filter service indicator that monitor air filter restriction and indicates when the air filter should be serviced. As the air filter gets dirty, the yellow position indicator moves in the clear window of the service indicator and locks at the highest point. It can be read even after the engine is turned off. The air filter should not be cleaned until the yellow position indicator reaches the red zone.

Saved money, gas and time ordering from K&N and not going to my local auto parts store. Thanks

Better than guessing if your filter needs cleaning or replacing.

Added one of these to my factory air box on my 2014 Mazda 3. No guessing on when to replace or clean my air filter. I like that K&N's version of the filter minder shows red at 10 h2O vs 15 or, 25. I did find it hard to find a 11/16 dril bit though. Lukly I remembered I had a Uni-Bit in my tool box.
