Innovate Motorsports 3729 Heat-Sink Bung Extender HBX-1 for Wideband O2 Sensors

Manufacturer

Innovate Motorsports

<p>Innovate Motorsports has earned its reputation as a pioneer in digital tuning technology for internal combustion engines. Since establishing their headquarters in Sycamore, Illinois, the company has revolutionized how enthusiasts and professionals measure, monitor, and optimize engine performance through innovative digital circuitry that surpasses traditional analog designs.</p><h3>Precision Measurement Technology</h3><p>At the heart of Innovate's product lineup is their groundbreaking wideband oxygen sensor technology. The company developed patent-pending digital circuits that deliver unprecedented accuracy in measuring air-to-fuel ratios, a critical parameter for achieving optimal engine performance, fuel economy, and reliability. Unlike older analog systems that suffer from signal degradation and calibration drift, Innovate's digital approach provides stable, repeatable measurements that tuners can trust.</p><p>The brand's <a href="/345-innovate-motorsports-air-fuel-ratio-gauge-16851">Air / Fuel Ratio Gauge</a> systems represent the gold standard for real-time mixture monitoring, offering professional-grade accuracy in packages suitable for both street and competition applications. These instruments use advanced Bosch LSU 4.9 wideband sensors coupled with Innovate's proprietary digital signal processing to deliver readings across the entire tuning range, from rich startup conditions to lean cruise settings.</p><h3>Data Acquisition and Analysis</h3><p>Beyond standalone gauges, Innovate Motorsports offers comprehensive <a href="/345-innovate-motorsports-data-acquisition-module-20121">Data Acquisition Module</a> solutions that enable tuners to log multiple engine parameters simultaneously. These systems integrate seamlessly with laptop computers and mobile devices, transforming raw sensor data into actionable insights through intuitive software interfaces. The ability to overlay air/fuel ratio data with RPM, throttle position, boost pressure, and other inputs makes it possible to identify tuning issues that would be impossible to spot with analog gauges alone.</p><h3>Expandable Sensor Networks</h3><p>Understanding that serious tuning requires monitoring multiple parameters, Innovate developed modular systems that use <a href="/345-innovate-motorsports-gauge-resistor-47908">Gauge Resistor</a> components and digital communication protocols to daisy-chain multiple sensors together. This architecture allows a single display unit to coordinate with numerous wideband controllers, exhaust gas temperature probes, and pressure sensors without requiring separate gauge clusters that clutter dashboard real estate.</p><h3>Universal Compatibility</h3><p>Innovate Motorsports designs their products as universal solutions compatible with virtually any internal combustion engine, from carbureted classics to modern fuel-injected performance builds. Whether you're tuning a turbocharged import, naturally aspirated domestic V8, motorcycle, marine engine, or industrial power plant, Innovate's tools provide the precise feedback needed to dial in performance safely. The company's commitment to supporting the tuning community extends beyond hardware to include regular firmware updates, comprehensive technical documentation, and active user forums where enthusiasts share calibration strategies and troubleshooting tips.</p>

Product Details

The Innovate Motorsports HBX-1 Heat-Sink Bung Extender is a precision-machined solution designed to protect wideband oxygen sensors in high-temperature exhaust applications. The Bosch LSU4.2 and LSU4.9 wideband O2 sensors are rated to operate at exhaust gas temperatures below 1,700?F (930?C) and sensor housing temperatures below 1,058?F (570?C) measured at the hex. When these temperature ranges are exceeded, sensor accuracy suffers and lifespan is significantly reduced.

Innovate Motorsports products display an error message (08-Sensor Timing Error) under excessive temperature conditions rather than provide inaccurate readings. For turbo vehicles, rotary engines, and other specialty setups, this error can occur frequently due to extreme operating conditions.

Key Features:

  • Constructed from cast stainless steel for durability and heat resistance
  • Specialty heat sink design pulls the sensor further from the exhaust stream while maintaining correct gas flow for accurate readings
  • Patent-pending Venturi-effect design ensures proper exhaust flow to sensor
  • Compatible with Bosch LSU4.2 and LSU4.9 wideband O2 sensors
  • Ideal for high-temperature applications including turbocharged and rotary engines

This bung extender provides thermal isolation in applications where pipe temperatures exceed safe operating limits, extending sensor life and maintaining measurement accuracy. Installation of the Heat-Sink Bung Extender is relatively simple.

EASY TO ORDER

Didnt know it was shipping from the manufaturer and in route but showed up unexpected on a monday after a snowstorm so not bad

The product was a perfect fit!

I was under the impression by 24hr shipping that i would get it the next day. But, turns out that it "leaves" with in 24 hrs and can take 3-10 days to arrive. It's a little misleading, but I did receive it in 3 days, so I'm "ok" with the delivery time (that is why i gave it 4 stars). 10 days would have been an issue.

Great price on item ordered. Delivery was very quick. 2 days. Surprised I did not hear or know about Autoplicity sooner.

The web site and the selection of the product is a great experience and the ease of using the site was great.

Fast shipping cheapest I could find, easy to deal with, great product

Ordered Sunday and recieved product Tuesday .. What more can u ask for? Great Seller!

Great product, looked evey where for the right brand on my spedomder cable. Product worked as advertised!! Look forward to working with guys again. Thanks

We ordered a cover for a pickup truck bed and were so pleased that it was shipped so quickly. The price was the lowest that we found on the internet or in any of the stores where we looked. We were notified by e-mail as soon as it shipped. We will definitely shop this site again.
