What does "WXF 60 comp" mean?

[jrobe]

I just bought a 97 Outback and under the hood on the radiator support is says "WXF 60 comp" written in grease pen.

Does anyone have a clue on what that means?

Thanks Jrobe

i used to work in a garage and sometimes the mechanics would write notes or reminders about the car so they would remember something. i would think its that
