Different part numbers, but it might still work. Call a shop.

any idea on who mite know for sure...i called my local shops, but none of them had any idea (i live in small town in south dakota).....closest subie dealer (like 200 miles away) told me they have different part #'s, that's all they would say

Just call any well known Subaru performance shop until one can give you an answer.

Just realized the sensor in my previous post is rear o2 sensor NOT the front. You need this:

And yes the 04 STi and 03 WRX cross referenced the same.

Are you talking the EGT sensor in the up pipe?

The other sensors you need to use the (for your year) stock OEM Denso units, which are like $189 each. Any other sensor will throw a code. I was told that by a very smart man, & I spent several trips to the car shop, only to prove him right. It sucks, but has to be the oem Denso which are twice the cost of "generics."
