Taking the core features from AutoMeter’s Pro Wideband, the Street Wideband provides the most important functions necessary to make sure you’re extracting the most power possible, safely. Our advanced auto calibration system automatically calibrates your gauge on every startup to assure you of the highest degree of accuracy over the entire lifespan of your sensor (no free air calibration is ever necessary). Designed for gasoline applications, this wideband gauge provides the same degree of accuracy and response as the Pro version, but at a reduced cost. Data logging output is included for one wire or two wire systems. Our specially designed O2 sensor and wiring harness are included for ease of installation.

I have a rear engine car. Is the wiring from the exhaust sensor long enough so the gauge can be mounted on my dash. If not will splicing the harness to make it longer effect it's operation.

Asked by: Mike B
Thank you for your question. You will need P/N: 5252 to have the correct length needed.

Is it possible to just order the gauge? I already have the LSU 4.9 sensor, SS bung, and controller purchased separately.

Asked by: alpine615
Thank you for your question. Unfortunately, we do not sell just the gauge head separately. 2679 always comes with the sending unit, wire harness, M18x1.5 fitting and the mounting hardware.
