Helly everyone
does anyone have a diagram/layout for the exhaust for 2006 NA 2.0l Auto?
My fuel economy hasn't improved after changing plugs, air filter, ecu reset, "Italian tune-up", and STP fuel line cleaner treatment. Based on the knowledgeable input from the guys and ladies here, the O2 sensor is the next thing to check.
However, when I look under the engine, both sensors appear to be on the same spot, about 8 inches from each other. I'm not sure if this is the CAT or just the elbow/bend. Also to make things more difficult, they both are positioned the same, ie not vertical nor horizontal(which I read somewhere indicates if it's front or rear)
Thanks for any help offered!

It would appear that the N/A exhaust layout changed with the MY06 to that attached (and the engine goes to DOHC).................



22641 on the picture is the "Sensor Assembly-Air/fuel ratio" 22641AA381
22690 on the above is the "Sensor Assembly-Oxygen" 22690AA831

Thanks again don! You really know how to get info.
I checked both links and the prices are reallygood compared to the
dealers!
The other picture seems to have a collar or an oversized washer, is that
something I need to remove before fitting? The other one indicates "manual
only". Are these sensors manual or auto specific, or swappable?
I've got an automatic. Thank you.

I checked for both and they are the same.

The picture with the shield/collar seems to be for illustration only. Not seem a Subaru one like that.
