Wideband AFR Gauge
A Wideband O2 air/fuel ratio UEGO (Universal Exhaust Gas Oxygen) gauge is a must have if you want to maximize your engine's power and safety. When tuning an engine, accurate air/fuel ratio data is critical because running too rich of an AFR can cause a loss of power, and running a lean AFR can result in serious engine damage. The unit's 52mm (2-1/16 in.) gauge housing works with most gauge pods and can be remotely mounted virtually in any location. It unites accuracy, speed, and control with an easy to read, digital LED display and sweeping LED needle that changes colors when the AFR changes from rich to lean.

AEM's legendary Wideband O2 Air/Fuel UEGO Gauge unites unsurpassed accuracy, speed and control with an easy to read, digital interface. This gauge-type controller features a digital LED display and sweeping LED "needle" that changes colors as AFR changes from rich to lean. The unit's 52mm (2-1/16") gauge housing fits in most gauge pods and can be remotely mounted virtually anywhere. All AEM digital gauges feature a 0-5v analog output for use with data loggers and virtually any engine management system, such as the AEM EMS or FIC.
FAST, ACCURATE AIR/FUEL DATA: AEM's world famous Wideband O2 UEGO Gauge is a must for anyone looking to maximize engine power and safety. When tuning an engine, accurate Air/Fuel Ratio data is critical. Running rich can cause a loss in power, while running too lean may result in serious engine damage. The AEM Wideband O2 UEGO Gauge features large LED numerals which enable the user to see when there's even a .1 change in ratio, providing time to shut things down before damage occurs. Each gauge comes with interchangeable black and silver bezels and black and white gauge faceplates for multiple color combinations.
The Bosch 4.9LSU sensor, which gives the controller its speed and accuracy, is laboratory calibrated at the factory and never requires free air calibration when used with an AEM Controller!

One line says sensor not included. Another says Bosch sensor included. Which is it?
WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
