VT O2 Sensors - Bosch?

[Mick1988]

Hi guys, in the process of cleaning my plenum chamber, throttle body and intake piping to increase fuel economy and also remedy a slight shudder at idle. I thought that replacing the O2 sensors while I'm at it would be a good idea since the car has done 245,000km and they're the only part of a major overhaul that I haven't changed.

Since GM branded sensors are well over $100 each, I've done a bit of research and found a pair of Bosch ones for $103 delivered to my door. 2 x HOLDEN OXYGEN SENSOR - VS VT VX VY VZ VE - BOSCH (eBay item 310220712100 end time 12-Apr-11 14:42:34 AEST) : Cars, Bikes, Boats

Just wanting someone who can confirm for me that the genuine sensors are actually Bosch sensors which - to my knowledge - they are.

Cheers in advance

Awesome, thanks a lot. I did work out that the Ecotec ones were different so I'll have to try to source them. Cheers mate.

They should be easily obtainable though eBay, or even eBay USA, Repco, Autobarn, Supercheap, and many more.
