Perfect replacement for my SCG-1.
My boost gauge was reading an error code "02 E8" which meant two things: - The sensor itself was bad. I cleaned it, it still read error message. - The circuit went bad. The second one was the cause after checking voltage to the unit. Bought this replacement, calibrated it, and it worked perfectly. Back to reading my AFR accurately on both 91 and E85.

well made, I keep a spare, as they do wear out.

Third o2 sensor
I figured a used one already went through the trenches. Installed it with a bung extension. Working as it should. Let’s see how long it lasts

Avoid this product. It WILL let you down.
Do not buy this sensor or Innovate controller that contains this sensor. I have replaced this sensor 3 times already over the course of 3 years due to E8 errors (Sensor Failure) and now have another only 8 months later. This is on a non-turbo, daily driven, pump gas car. These sensors do not last and Innovate does not warranty the sensor. Stay far, far away from Innovate. Now I am fighting with the extended warranty that I purchased from Amazon which I purchased because according to the warrenter the product must have a manufactures warranty for them to consider coverage. From the Innovate Manual on the LC-2 Exclusions From This Warranty Oxygen Sensors are excluded from this warranty

works as replacement for aem x series wideband
the sensor for one of my aem x series widebands went bad & would peg lean at all times. the innovate sensor was the fastest available one so i took a chance figuring it would work and it works just as well as the original aem sensor. the cable on the innovate may be a little longer than the aem one so thats a plus for anyone looking at this as a replacement too

Accurate and great
As described - I wish the threads were a bit stronger. Works great. 5 stars if it would have had beefier threads that don’t strip so easy.

Quality is not what it used to be with Bosch.
I use these for an air fuel ratio gauge and my truck usually eats these for breakfast. The longevity is just not there like it used to be with Bosch.

these are the real deal
I use these with an Innovate LM-2 unit on my engine dyno. The dyno is hard on the sensors, so I have to replace them often. I've tried the "no name" replacements and they just don't last at all. These from Innovate last way longer than the cheap knock offs...
