O2 sensors

Guys I am looking to change my O2 sensors.
I have looked through previous threads and found a site recommended called BuyPartBy they list 4 sensors and a flange kit
Can you tell me what sensors I require and do I need to get a flange kit ?
I would like to get new first, before I pull them out, cheers !
Silly question, where is the oil filter located ? And how do you get to it ? As I cannot seem to find it !
Thanxs guys

Flange kit - urm i change mine a few months back and ive no idea what one is if that helps

You need a 4 wire universal one - wireing is simple ...

Oil filter is hidden away behind the black plactic bits at the front of the engine bay slight right of centre when viewing from laying on the floor You can normally get your hand in to unscrew without taking them off.

enjoy ...

You don't need a flange kit.. just the sensors..
The sensors themselves are identical.. the genuine ones are not. (the wires are longer for the rear one)

The colours of the wires are the same, (they are the same make as genuine ones) and its just a case of measuring, and soldering the old connector onto the new sensors.. everything is included in the box.

The front one is very easy to do, the rear is a pain in the rear

check this site.

the ones you want are 4 wire universal.. £25.58 + vat each.

The original Mazda ones are very expensive, and these are made by the same company.

just solder the original connectors on to these, the colours of the wires are the same.
