Factory and aftermarket mass air meters have long been a source of frustration for tuners. The JMS Mass Air Modifier is the only product that can filter the mass air signal, while also scaling the signal to extend the dynamic range of the sensor. Cold air kits, camshafts, and the architecture of your air inlet on a turbo or supercharging system are just a few examples of what can cause turbulent airflow and a noisy mass air signal.
By filtering the MAF signal you can clean up a "noisy" signal area that may be causing a drivability issue. The JMS Mass Air Modifier features a simple switch that allows you to choose between filtering the signal at idle or cruise.
The JMS Mass Air Modifier features advanced electronics housed in an aluminum case, a complete OEM-grade plug and play wiring harness using shielded cable, with additional cables for 0-5 volt signal input and optional on-board enable/disable switch.
