Official Release:

MSD Standalone Air/Fuel Wideband 02 Gauges Kits are extremely accurate and compatible with both EFI and carbureted fuel systems. Available in black- and white-face versions, these feature-packed analog-style standalone gauges measure 2-1/16-inch in a slim-style package that takes up very little dash space. Their easy-to-read analog dial includes a 270-degree sweep pointer from 6 o’clock to 3 o’clock, and an internal microprocessor controls pointer movement to ensure accurate movement in street, off-road, and race conditions. For virtually limitless mounting options, a five-foot-long six-pin weathertight sensor harness and four-foot power/ground/lighting harness is included. An adjustable LED warning light allows you to set both low and high trigger points, and a peak recall button displays min/max gauge readings. The Bosch LSU 4.9 wideband O2 sensor is compatible with all fuel types – leaded, unleaded, E85, diesel, and even methanol.
