Ok new to this. I have an engine check light on my 2004 impreza wrx. Its sensor one pre cat air fuel sensor. I have been told genuine sensors are best. Now subaru as we all know want £350 for one

(Subaru part number - 22641AA042).

I know denso make the OEM sensor and have been told there own part number is

Denso 234-9011.

I was about to buy one off amazon USA for £98 posted. After calling my local auto parts dealer they say a denso DOX-0306 will fit for £80 instock.

What is the difference between a denso 234-9011 that everyone seems to fit and a denso dox-0306. Is it just a uk part number?

Any help would be great.

Fitted the sensor today. Easy to do. Wheel off, small splash guard on arch liner off, few clips on under tray off. Bend the under-tray out the way and away you go. Just driven it for 30mins on the bypass and a quick razz. Turned the engine off then back on and the light it now off. WINNER.
