As an additional point, possibly of interest, the retail price quoted for the 750mm lead-equipped sensor was ~$250, while the post-cat sensors with a shorter lead retail for ~$149. It sounds like one expensive run of wires!

Thanks in advance.

I asume for a S52. The 990 mm one is 11 78 1 437 943. The 660 mm one is 11 78 1 406 981. Both retail for $133.35 each.
