So digging around various parts sites I notice your PFL V6 o2 sensor p/n is 90509169, which corresponds to Bosch p/n 0258003447

However, theres also listed an o2 sensor which fits Vectra, Sintra and Calibra 2.5 V6s (Bosch p/n 0258003765, Vx p/n 855338 , 90541930 , 90570582)....anyone have any good reason why they shouldn't be interchangeable? I mean they're literally the same engine. All 3 wire, same multiplug by the looks of it.

EPC doesn't seem to have any cross-pollination, but my usual example is HT leads - Vectra B ones are a totally different p/n but they do fit, even though 'computer says no.' 

Anyone got any thoughts?!

Variation is typically cable length to suit the logistics of each installation

hmmm... what I was suspecting, then.. perfect example being the 'aforementioned' HTs, same thing, really. 


I might just go for this other 02 sensor, if noone can see any instance where it's going to be wrong. (looking at pics, cable length looks identical/near enough to Omega version)

EPC states this (90541930) is 'FOR LEADED FUEL MODIFICATIONS,GULF COUNTRIES' so thats possibly ended that, then....
