    Extend Dynamic Sensor Range. This JMS Analog Mass Air Modifier is the only product that can scale the signal to extend the dynamic range of the sensor while filtering the mass air signal. Camshafts and air kits are just a few examples of what can cause a noisy mass air signal and turbulent airflow.

    Quality Construction. This JMS Mass Air Modifier features a complete OEM-grade plug-and-play wiring harness using shielded cable, advanced electronics housed in an aluminum case and 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, and 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.

    1-Year Manufacturer Warranty. The Mass Air Modifier Product 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 Analog Mass Air Modifier fits all 1988-1995 Ford Mustang.

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