Filter Minder - Air Filter Restriction Gauge

Shipping calculated at checkout.

This Filter Minder attaches to our FR or FS canister air filter upgrade kits. The air restriction gauge shows you the condition of your air filter without having to open the canister. This is an easy, foolproof way to know when it's time to replace your air filter. 

To install this gauge on your canister, just remove the plastic plug in the elbow on the end of the canister housing. Then just screw this gauge in and tighten by hand only - DO NOT OVERTIGHTEN. To reset the gauge after replacing the air filter, just press the yellow button on the end of the Filter Minder.

Air Filter Restriction Gage

It was a good add on for Kawasaki FR Series Air Filter Kit. Haven't had it long enough to give a complete review, but have used these for heavy equipment and they do work.

Bought the whole air cleaner upgrade kit. Filter minder makes it complete. Happy so far, but filter system hasn't needed cleaned yet either. Fingers crossed it works as advertised. Looks great so far...
