Have a few 97 Legacy Outback 2.5 AT used parts i got for free wondering if anyone knew if they could be used on my 96 Legacy Sedan 2.2 SOHC MT if needed, most importantly the IAC Valve, as it is a good unit and part stores charge ungodly amounts for them, as well as the Separator Plate/Oil Baffle (Metal) from the 2.5 to replace the plastic one on my 2.2. Also would certain really expensive emission related parts work from a 2.5 to 2.2, including MAF, EGR valve, TPS sensor, Fuel Pressure Regulator. Thanks

I do believe everything you mentioned WILL swap.

Yeah all that should swap just fine.

 

When electronic parts (sensors) changed they generally changed the connector on the engine wire harness. If the part can physically plug into your harness, chances are good that it will work.

The MAF sensors had a couple different designs. I don't know exact details on which years had which parts, but they will have a sticker on the side with Subarus 10 digit part number on them. Something along the lines of 22880 AA160 is on your 96 2.2. If the MAF from the 97 has that part number it will work just fine.
