My Impreza UK turbo MY00 needs a new lambda sensor, The genuine Subaru one is a 22690AA321 which is around £152+vat, However "Just Lambda" do a Walker sensor, part number 250-23088 which they say is a direct replacement for the original for only £65 all in!
Has anyone ever fitted one of these and if so have they had any problems with it, mainly being did it pass the UK MOT emissions.
Please help.

I use the same one in mine for a fair amount of time and we've sold a fair few now too. We only sell them for Imprezas, so they are tried and tested.

 

Is this a universal type sensor as it doesn't appear to have a plug?
The Walker sensor 250-23088 is fitted with a plug.

 

You can pick up universal ones for£20 - £30,however you will have to either cut the wires or remove the pins from your old plug,the one you need should be a 4 pin plug with 3 wires going to the sensor ,I picked one up today £49.00 + vat.
