Review on Innovate Motorsports 3888: Upgrade Your Oxygen Sensor with a Replacement Sensor by Christopher Holker

I would expect it to last a reasonable amount of time as it's at the top of the price spectrum. My previous sensor lasted about 7 years on two different cars and three engines, two of which were turbocharged. I installed this sensor and it is perfectly calibrated. I drove 70 miles total and read AFR at 12.5-15.2 most of the time and 11.5 at 20+ psi maybe twice in that time. The sensor died giving me "E8" from time to time and the rest of the time it got stuck at 22.4. Tried several times to recalibrate - without success. I think it's time to buy another sensor.
