GlowShifts 52mm Blue Digital LED Air / Fuel Ratio Gauge offers a collection of high end automotive features including a blue LED readout, a sleek ultra thin design and a tinted lens. This model will precisely monitor the air / fuel level within your engine that is within a range of 10.0 to 20.0 AFR to help you determine if you are running a lean, optimal or rich mixture. This series is fully electronic with a blue digital LED readout, which allows for easy viewing at all angles during any lighting conditions. Each gauge includes all necessary mounting and installation hardware to hook your gauge directly into your narrowband oxygen sensor. Also included is a feature allowing your gauge to dim for night driving when your headlights have been switched on. When powering up your Blue Digital gauge, the user will be alerted to a startup sequence to ensure your gauge is functioning properly and that it is calibrated correctly. The lightweight construction makes the gauge weigh in at only two ounces and one inch in length. GlowShift stands by every gauge with a one year warranty and free technical support.
