Lambda sensors

[identiti66]

Are the front and rear O2 sensors different on the 2.2 (Vectra B if it makes a difference)?

Looking on ECP there's a few different NGK ones listed going from £73 each up to £105 each
S'a lot of dosh.. anyone got the NGK part number stashed in their grey matter?
I want to change mine at some point soon-ish.

ntk are the factory fitted ones there different plugs and wire lengths altho the narrow band sensor itself is the same

got my ntk one for £59 from euroshitcarparts

So the business ends are identical, just the plugs and length of wire aren't.. yet the 2 different part numbers have a price difference of ~£20.. that sucks.

For info (mainly mine).. the numbers are:
FRONT - OZA531-GM6 / 1869 .
REAR = OZA531-GM3 /1864

Cheapest I can find at the moment totals nearly £130 for both.

the front one is the important one

you could get a cheap aftermarket one for the rear and cut/solder it in

That's good to know...
See what gives when the evenings get lighter again, I'd rather do it properly if I can but there's a lot planned for the next 6 months

Quite a big saving over ECP
