Exactly as described. Eliminated my knock sensor code. Just s real pain in the ass to fit cos you’ve got to remove one of the coolant tubes in order to get the socket on there correctly

Went OEM because this sensor is a bear to get to on my engine (M62tu). Solved the problem. Easy to replace once you get there. Sure hope it lasts as long as the original which was there 14 years.

Perfect replacement for my '03 540i. I couldn't pass up replacing these while doing the tear down for my failed timing guide rails repair. Best price on the web.
