      Get Accurate Setting. This JMS Digital Mass Air Modifier filters the mass air signal in your vehicle, which greatly improve the cruising and idling performance of your engine. Scale and filter the mass air signal in real time on the dyno to save time and provide accurate settings.

      Quality Construction. This JMS Mass Air Modifier features a complete OEM-grade plug-and-play wiring harness that uses shielded cable, advanced electronics housed in an aluminum case, and has an optional onboard enable/disable switch.

      Clean Up Noisy Signal. Clean up a "noisy" signal area that might be causing a drivability issue by filtering the MAF signal. With a rotary switch, you can choose between 16 built-in levels of filtering to quickly change the mass air signal on the dyno in real-time, plus you can see immediate results through OBD-II data logging. With unique filter ranges, you can fine-tune the filter to your problem area. The device operating voltage range is 9.5-20 volts DC, and it is compatible with 12V or 16V DC power systems.

      Plug-and-Play Installation. Easy to install plug-and-play design utilizes OEM connectors to eliminate splicing into factory wiring harness, making the process a breeze.

      1-Year Manufacturer Warranty. The Mass Air Modifier comes with a one-year limited warranty against any defects in materials or workmanship. Please check the manufacturer's warranty page for full details on the terms and conditions.

      Application. This JMS Digital Mass Air Modifier fits all 2005-2010 Ford Mustangs.

      Note: Not legal for sale or use in California or on pollution-controlled vehicles.
