Innovate HBX-1 (Heat-Sink Bung Extender). Reduces sensor temperature for accurate readings.

Key Features

  • The HBX-1 Heat-Sink Bung Extender pulls the O2 sensor 1.1875" (30mm) out of the original weld boss.
  • This design reduces the applied temperature to the sensor.
  • It maintains critical flow of exhaust gases to the sensing element for accurate readings.
  • The bung extender is precision machined from specialty materials.
  • It is designed to address applications generating excessive heat in the O2 sensor.

Product Details

The Innovate HBX-1 Heat-Sink Bung Extender is precision machined to help keep your Bosch LSU 4.2 or 4.9 wide-band O2 sensor operating within its ideal temperature range. These sensors are rated for exhaust gas temperatures below 1,700°F and sensor housing temperatures below 1,058°F. When these limits are exceeded, accuracy suffers and the sensor's lifespan can be significantly reduced. Innovate Motorsports products will display an error message, like the '08- Sensor Timing Error,' rather than provide bad data.

For certain turbo vehicles, rotary engines, or other setups that run exceptionally hot, encountering these temperature issues can be frequent. The HBX-1 addresses this by using a specialized heat-sink design. It effectively pulls the O2 sensor about 1.1875 inches (30mm) away from the direct exhaust stream, which helps reduce the temperature applied to the sensor. Crucially, it's designed to maintain the proper flow of exhaust gases to the sensing element, ensuring you still get accurate readings without the excessive heat.
