Hi,
It's been a while since last time I posted here. Can't work on the car, I'm on a ship since June and until November.
However I'm starting to order some parts.
I've seen on eBay a guy selling NGK NTK o2 sensors, left and right have different numbers. Haven't touched the ZR-1 since a while but if I recall, both left and right are supposed to be the same, right?

Thanks for your help!
