AEM 30-5121 - Filter Minder Restriction Gauge
AEM Filter Minder Restriction Gauges let you know when it is time to service your air filter by monitoring airflow and the gradual increase of air filter restriction. The gauge's needle will move from the green section, through the yellow section, and to the red section as the air filter starts to load with dirt and faces greater restriction.
Key Features:
- Filter Minder Restriction Gauge Kit
- Remote Mounted
- 20 in. H2O
- Incl. 20 in. Filter Minder/Hose/Hardware
Note: TDot Performance is an authorized AEM dealer, so your new Gauge includes the full factory warranty. What more? We are proudly Canadian but have warehouses in both Canada & USA, so whether you are Canadian or American, you WILL NOT pay any Custom, Duties or Brokerage fees!

AEM was founded in 1987 as a tuning performance shop in Compton California by John Concialdi and Bob Sullivan. AEM tirelessly dyno tested and worked closely with racers and auto manufacturers in an effort to understand intake energy dynamics. This resulted in the sale of their first air intake kit in 1994. Today AEM is recognized worldwide for their innovative products.
