AEM Bosch LSU 4.9 Replacement O2 Sensor
AEM's Bosch 4.9LSU Wideband UEGO O2 replacement sensor kit includes only the sensor (with attached cable and male connector) and is intended to replace an existing mounted wideband sensor used with AEM Digital Wideband UEGO Air/Fuel Controller Part Number 30-4110.
These sensors have a laser-etched, calibrated resistor in the sensor's connector body. This resistor is specifically created for the exact sensor that it is attached to. Modifying this will invalidate the sensor's output. The wideband sensor is laboratory-calibrated at the Bosch factory, accurate to 0.1 AFR and never requires free-air calibration when used with an AEM wideband AFR controller.

Part is great does what it's suppose to do. Just a bummer my evo runs through them though. Seems like every once a year I'm replacing one.
I've had my original AEM Wideband gauge for about 3 years. Worked great. A several weeks ago it started reading is was running a little rich. I was worried but not to alarmed because we all know running rich is better than lean but I was still concerned maybe I had a leak of some kind. I did, completely unrelated but was informed the O2 sensors last maybe 2-3 oil changes. It lasted more than 3 years. Called into MAP and they found the replacement sensor got to my home FAST!!! Replaced the sensor a couple days later myself, everything reads normal now! THANKS MAP!!
Package arrived earlier then expected! Quality service and quality replacement sensor
Exactly what I needed and shipping was quick so it got me back on the road quicker than I thought I would be!
What I love about map is that I know this sensor is 100% legitimate. Even Amazon is having issues with knock offs that only last a few days.
