Description

The Innovate Heat Sink Bung Extender (HBX-1) is engineered to protect your wideband O2 sensor from excessive heat and extend its life in high-temperature applications. The HBX-1 features an innovative heat sink design that dissipates heat away from the sensor, making it an essential accessory for turbocharged or high-performance vehicles with elevated exhaust gas temperatures. The extender moves the O2 sensor further from the exhaust stream, reducing the likelihood of overheating while maintaining accurate air-fuel ratio readings.

Key Features:

  • Heat Dissipation: Innovative heat sink design disperses excessive heat from the sensor to prevent damage and extend its operational life
  • Sensor Protection: Ideal for turbocharged or high-performance applications where high exhaust gas temperatures can shorten sensor life
  • Extended Length: Moves the sensor further from the exhaust stream, reducing direct heat exposure while maintaining optimal AFR readings
  • Durable Construction: Made from high-quality materials to withstand extreme exhaust temperatures and ensure long-lasting performance
  • Easy Installation: Installs quickly onto existing M18x1.5 bungs, making it compatible with most wideband O2 sensor setups

Specifications:

  • Material: High-temperature resistant steel
  • Thread Size: Standard M18x1.5 thread
  • Length: Approximately 1 inch
  • Application: Wideband O2 sensors, particularly in high-performance or turbocharged vehicles

Included in Box:

  • Innovate Motorsports Heat Sink Bung Extender (HBX-1)

Additional Information:

  • Protects Sensors: Helps prolong the life of Bosch LSU 4.2 and 4.9 wideband sensors by preventing heat damage in high-temperature environments
  • High-Performance Ready: Designed for vehicles with forced induction or extreme exhaust conditions, where managing sensor temperature is critical
  • Wide Compatibility: Works with Innovate Motorsports wideband controllers and other wideband O2 systems utilizing M18x1.5 threads

What O2 sensors does this work with?

  • It has an M18 x 1.5 thread that is an industry standard.  It is compatible with all Innovate Motorsports wideband sensors and bungs.  It will accept Bosch LSU 4.2 and 4.9 widebands, NTK widebands, and most narrow band sensors as well.  There are a few narrowband o2 sensors and bungs out there that use a smaller thread, but those are somewhat rare.

Questions & Answers

    How long is the extension from the copper gasket to the outer end? That is, how far from the bung seat does this move the O2 sensor. I have space issues to fit this and the O2 sensor into.
