I know this is a bit off on what you guys are talking about, but I have a 97 impreza outback sport (has a big cosmetic hood scoop) and it was recalled:
(the recall fix was putting a piece of tape over a couple holes...)
"97 RED ALERT!
Subaru of America, Inc, has determined that some 1997 model Subaru Impreza Outback Sport 2.2L vehicles may experience corrosion of the oxygen sensor wiring harness connector due to water drainage from the hood scoop air duct. Under this condition, your vehicles On-Board Diagnostic (OBD) system will illuminate the "CHECK ENGINE" light on the dash indicating the need for prompt corrective action by your Subaru dealer.
WHAT YOU SHOULD DO:
To prevent this condition, you should immediately contact your Subaru Dealer for an appointment to modify the hood scoop air duct and the oxygen sensor wiring harness connector at no cost to you. The approximate time to perform this repair is less than 40 minutes. However, it may be necessary for you to leave your vehicle the full day of your scheduled appointment to allow your dealer some flexibility in scheduling other customers. Should you have any questions regarding this, please contact your nearest Subaru Dealer or Subaru of America, Inc., at 1-800-782-2783 (1-800-SUBARU3). "
just thought I'd mention it incase anyone was thinking of opening up their scoop on an obs,(I did as soon as I bought the car in 04 but then I read about the recall and closed it back up) don't think it applies to the regular outback wagons, but who knows?
