I have a set of four (4) Five-O Motorsports Subaru 1200cc Sidefeed Injectors. They came with my Legacy GT when I bought it. I've swapped back to stock injectors as these were way more than my needs. They sell new for $400. They have less than 10k miles on them. One injector has two small gouges on top from removal (can be seen in second picture, second injector). My mechanic assured me it would not affect performance. I'm looking to get $300 plus shipping and paypal. I'm in Denver if you'd like to pickup locally.
