Didn't work in oxygen

Didn't work. It took me too long to install and test it so it's my fault I can't get a refund but the thing doesn't even work.

Pros
  • GOLS certified
Cons
  • Some disadvantages

Perfect replacement for AEM Bosch

Product replaces sensor AEM 4110. Works great. I rode it for almost a year across the US with almost no problems. Would buy again.

Pros
  • Excellent construction
Cons
  • Quality

Excellent purchase! suitable for oxygen

just changed the upper standard O2 sensor at 70000km. I installed this sensor myself after diagnosing a check engine light that came on intermittently along with poor fuel economy. It's been 2 days now, fuel economy has improved as has general ride and idling. Everything is smoother now.

Pros
  • Absolutely amazing!
Cons
  • It was possible to choose a newer model

Failed 7 passes in 48 hours

I don't normally do product reviews. I felt this sensor needed it. Delivery was fast. Installation was easy. However, the sensor held out 7 passes per 1/8 mile when setting. There were no exact values, they would change without changing the tune. Appears when tilted above 4,000 rpm. A passage, then the path to riches, turning 2 hot circles. Wouldn't recommend it.

Pros
  • Consistent test results
Cons
  • Unbelievable price

Sensor broken on arrival

I bought this to replace the famous Bosch brand 17025 that is used with the Holley Sniper EFI system. The car had a notoriously good set-up which should have an idle AFR of around 13.5:1. On the first run, this sensor gave erratic readings, going from very lean (35.6) to very rich quickly, almost like a narrow-band sensor. I confirmed the erroneous readings by connecting my laptop to the ECU (see fig.). Bought hoping to save some money on the sensor but obviously it was a mistake.

Pros
  • Very good price
Cons
  • There are new competitors
