Review on LSU 4.9 Lambda Wideband O2 Oxygen Sensor Replacement - Replaces 17025, 0258017025 - Compatible with AEM 30-4110, 30-0300, 30-0310 - X Series AFR Inline Controller - UEGO Air and Fuel Ratio Wideband by William Pacino

Bought 2 years ago and worked fine for a few months. It went badly and the company kept their guarantee and sent me a new one. This new sensor lasted a few more months before I damaged the wiring harness and sold the car. Today I bought a second one because the original sensor has worn out due to the cold. These sensors are extremely sensitive and the original sensors that come with broadband sensors will fail over time. This sensor worked just as well and won't hurt your wallet if it fails again.
