I don't know what the "originals" were... but NGK will work just fine.

The OEM plug in our '99 with the Phase I 2.5l is the NGK PFR5B-11, Subaru part number 22401AA570. I have had really good luck running these for 60k mile intervals. Unfortunately they are about $12.50 each.

I found the PFR5B-11 NGK at advanced auto for $10, best price I found, and yes those are the original equipment plugs for the car. List on those plugs most places is $15 each and a lot of the internet sources wanted $12 or more with shipping extra. My kid who is on a budget bought Autolite APP3924 for about $4 apiece. They are double platinum and made in america. Very high quality appearance and seemed to match the NGK's for dimensions very well. The car runs like it should on them, so they may be OK to use. The plugs on this engine are real difficult to change, so I bought the NGK not wanting to have to redo the job if there were any problems.
