Trusted by tuners. Since 2003 PLX widebands have tuned engines worldwide to run cleaner, operate more efficiently, and produce more power. Patented.

Fast and accurate - PLX widebands employ PID critically damped technology, are individually tested, and are accurate to less than 0.1AFR.

Plays nice - Works with gasoline, diesel, methanol, ethanol, LPG, Diesel, E85. 0-5V analog output interfaces with 3rd party ECU’s and data loggers.

Monitor sensor health - Proprietary IntelliHealth algorithm detects your sensor’s remaining life and reaction time.

Fully plug and play - Installation requires no manual calibration – simply install your sensor, connect the wire harness, and apply power.

Digital sensors - All sensor modules have a built in microprocessor designed display quick, accurate, ultra high resolution sensor readings.

Combo includes: multi-touch gauge, controller box, Bosch LSU4.9 sensor, sensor harness, and wire/connector kit. Don't forget to add an O2 bung or backup oxygen sensor.
