I sold a pair 4 years ago for 1k, 1.2 doesn't seem unreasonable I guess.
I was buying the parts today for an S54 inspection service, and the 6 rubber spark plug gaskets which were £8 each from bmw in '21 are now £28 Yeah, that's £153.26 (with the usual discount yay) for 6 small rubber rings :dizzy:
I tried to buy this on copart to save if from being broken but the price just went too high to make it viable to save for me. The pics on copart did look like OEM kit
