Have not had the opportunity to do so on a 2004, but I have changed plugs on a '96, '00, and '07. They are essentially the same. You will need to remove part of the air intake system and possibly battery and windshield washer reservoir. Plugs are in a deep well and having an assortment of socket extensions and accessories is essential. A long-tipped angled needle-nose pliers always comes in handy to fetch the socket and plug from the well. If you have a well equipped tool box and you have changed spark plugs on other vehicles you should be set. Good luck!

For a 1997 Subaru Outback, spark plugs should typically be changed every 30,000 to 60,000 miles, depending on the type of spark plugs used. If using standard copper spark plugs, more frequent changes closer to 30,000 miles are advised, while platinum or iridium plugs can last longer.
