Review on 🚀 NTK 25648 Oxygen Sensor: Enhance Fuel Efficiency and Performance by Gaurav Ansong

Super excited I was able to install this myself instead of taking the car to the dealer! However, be aware (on the Mini Cooper at least) that while technically easy to install and should take around 15 minutes, taking the old one out can be tricky. It took several hours to figure out how to get at the old sensor and have enough elbow room to get the sensor out. The car got noticeably better and after a few hundred kilometers there were no warning lights.
