Lingenfelter GM LS Series Engine Bosch Heated 02 Sensor

Proper O2 sensor operation requires temperatures of 600 degrees Fahrenheit to ensure correct readings to the computer. In some exhaust systems the O2 sensor is unable to reach this temperature due to reduced back-pressure or improper mounting location. This condition is most easily diagnosed from a recurrent SES light or when you observe the computer repeatedly switching between open and closed loop functions. To correct the problem LPE recommends and uses this high quality Bosch electrically heated O2 sensor to replace the stock sensor. The sensor mounts in the stock O2 bung and requires only minor wiring skills. This item not legal for sale or use on California pollution controlled motor vehicles.
