Just make sure you buy the correct Bosch sensor. FCPEURO has it wrongly listed. If you have a N63TU you need to get the Bosch 0 258 010 435 for the downstream sensors and not the 0 258 006 755 listed on FCPEURO. Those are for the original N63 engines (2012). This might be why some people are having overheating/resistance too high and intermittent problems with these downstream sensors.
