My local Advanced Auto had the NGK's. I put the +4's in my wife's 97 Outback. Had them in for 45K. No problems with them. They were OK nothing special. I took them out just before I traded it and they looked fine. It was obvious though that some of the electrodes were favored over others. I put the single plats in as a replacement. No real difference as far as I could tell.jersey judge said:same deal. Went to the locals, Pep Boys doesn't carry NGK's for ANY Subaru AT ALL. Went to the Bosch Platinum 4's. let's see how they work.
