Bora V5 O2 Sensor

[Mu5tank05]

Hello all,
Just after some assistance with working out the required O2 Sensor's for 2001 Bora V5 (AQN), I am looking for both the Pre and Post CAT sensors.
I have being looking on ECSTuning for the parts but are not sure which is correct
(ES#2539127)
(ES#8367)
Are the above two the right ones? and if so which is Pre and Post?
Thank's for your time
Edit: Any other suggestions of places to order such parts?

I have used CarPartsAustralia.com.au many years ago.
I was able to email them my VIN and they advised the correct part. Sensor was under $90 express post shipping about $10.

The GTI did not have a pre cat sensor, are you sure your Bora has 2 sensors ?

The VR5 is more likely to have two sensors because of it close relation to the VR6. I wouldn't buy engine related stuff for a V5 from ECS anyway - There are much better OEM aftermarket sellers based in Australia (Tooleys, Unique Auto Parts etc) and the VR5 models were never sold in the US.

ECS is great for suspension components and body parts tho.

Thanks guys I ended up buying both the sensors from https://www.carpartsaustralia.com.au/ and installed them weekend past, after clearing the ECU fuel usage is back down to 10L/100KM
