The Bosch LSU4.2 and LSU4.9 wide-band O2 sensors (shipped standard with Innovate Motorsport products) are rated to operate at an exhaust gas temperature of < 1,700 Fahrenheit (930 Celsius), and a sensor housing temperature of < 1,058 Fahrenheit (570 Celsius) measured at the hex, for maximum accuracy and control. When either of these operating temperature ranges is exceeded, the sensor can no longer be accurately controlled. Further, operating at or above these temperatures for any length of time can significantly reduce the life expectancy of the sensor. Innovate Motorsports products are designed to display an error message under these conditions (08- Sensor Timing Error) rather than provide inaccurate readings. For some turbo vehicles, rotary engines, and other specialty setups, this error message can be encountered with annoying frequency due to operating conditions specific to those engine types and configurations. This precision machined part is engineered to address applications generating excessive heat in the O2 sensor by utilizing a specialty heat sink design which pulls the sensor futher out of the exhaust stream while maintaining correct flow of exhaust gasses to the sensor for accurate readings.
- Specialized heat-sink design pulls sensor 1.1875" (30mm) out of original weld boss, reducing applied temperature to the sensor while maintaining critical flow of exhaust gasses to the sensing element for accurate readings.
