This heated wideband oxygen sensor is a direct replacement for the sensor built into AEM's 30-0300 X-Series Wideband UEGO AFR Gauge, restoring accurate air/fuel ratio readings once the original sensor wears out.

Replacement Sensor Specs:

• Drop-in replacement for the sensor supplied with the 30-0300 gauge kit.
• Faster signal response than a standard Bosch LSU 4.9 wideband sensor.
• Withstands both leaded and unleaded race fuels.
