“Perfect fit for my 2004 facelift R53 Mini Cooper S. Solved my fault that came up during a routine OBD2 scan. The price for two of the sensors is cheaper than directly buying from the main dealer and the part is just as good, infact it is the correct part.”

“New sensor has transformed the cars performance and driving quality Old sensor had been throwing cel and codes for a while but I kept resetting it then started misfiring under load and generally down on power”
