Product Description
Wideband Digital Air Fuel Ratio Gauge Kit EVO Series 52mm Blue Red Display - Automotive Oxygen Monitoring Component - Prosport Performance
- Dual Color Digital Display This digital air fuel ratio gauge features a selectable blue or red display that can be adjusted to suit different lighting preferences. The gauge remains blacked out when not in use and includes adjustable brightness to support visibility in various driving conditions without distracting the driver.
- Wideband Oxygen Sensor Included The kit includes a five-wire heated wideband oxygen sensor designed to provide consistent air fuel ratio readings during engine operation. The heated sensor supports stable measurement during cold starts and normal driving conditions across a broad AFR range.
- Compact 52mm Gauge Size Designed in a standard 52mm (2 1/16”) format, this gauge is suitable for common mounting locations such as dashboards, A-pillars, or gauge pods. The slim housing allows installation in areas with limited depth while maintaining a clean and unobtrusive appearance.
- Digital Readout with LED Indicator Ring The gauge displays numerical air fuel ratio values in the center with an outer LED indicator ring for additional visual reference. This layout allows drivers to monitor AFR information without prolonged focus away from the road.
- Complete Installation Kit Includes the digital AFR gauge, wideband oxygen sensor, weld-in bung, wiring harness, power harness, instructions, and decals. A 0–5 volt analog output is provided for compatibility with external data recording equipment where applicable.
Utilizing the latest Bosch wideband O2 sensor -5 wire heated LSU 4.9 (Prosport Inc. is the only one in the USA to use them) our gauge now has the widest range 10.0:1 to 20.0:1 AFR readings on the planet. Featuring a Dual color (Red or Blue) readout in the center of the gauge and a bar-graph syle LED's around the outside of the gauge for immediate reference to AFR.
