Made this list to help if you need a new oxygen sensor, all from varies post, thanks to Okibi, matty, 93clubman and others.
NA6 universal,single wire no plug.
Bosch P/N 0 258 986 501 36Y, without connector, use your old one
NTK P/N OZA401-E20 with connector. Manufactured by NGK
NTK P/N OZA624-E1 without connector, use your old one
NA8,NB8A,NB8B= 4 wire.
Bosch P/N 0 258 003 550 with connector
Bosch P/N 0 058 986 505 36Y universal LS05 NO connector, use your old one
Bosch P/N 0 258 986 507 36Y universal LS07 NO connector, use your old one.
With the 4 wire units the LS05 is the one closest to OEM but others have used the LS07 with no adverse effects noted.
Parts available from your local spare parts stores eg Repco, Auto One etc.

o2 sensors.
Doh!
I lost all my bookmarks the other day, and I had one with a good write-up of a conversion from 1-wire sensor to 4-wire sensor for an NA6.
It wasn't too hard to find, and from memory, it was a bloke in the UK.

o2 sensors.
Pardon my ignorance, but I've read a few things about CO sensors, and advice that it should be replaced f buying a second hand car...
My question is why?
I assume it has something to do with the fuel injection system(?)... are some O2 sensors better than the stock one? Should it be changed/upgraded in any way?
Again, I know nothing about this stuff, so anyone who can explain it would be owed a beer! ;)

o2 sensors.
Over time the o2 (oxygen) sensor reacts more slowly to fuel mixture changes until eventually it stops working all together. The o2 sensor is a key sensor used by the engine management system to set the fuel mixture. For optimal efficiency it's important to replace the o2 sensor before it starts to fail.

Re: o2 sensors.
Bumpage, the extractors i'm putting on the NB locate the O2 sensor further backward so think it's time to get an O2 sensor and make her fit.
The Bosch sensor pdf lists the "0 258 986 602" as the current part number for the NB, perhaps they've updated their catalogue (page 75).
Unless i'm mistaken it looks like the Early NBs (single O2) have the same sensor as the later NBs had post cat, and the later NBs have a different pre cat sensor.

If you had access to a car like this, would you take it back right away? Neither would I.
