Buying direct saves you heaps of cash, and places like greenline and perfect run are really good to deal with.

Just be careful about getting sard injectors for 99-00 EJ205's.. I've been searching for ages and been told only 850cc Sards fit 99-00 wrx's and that's only because they are made for STI's but will fit a standard wrx... Pretty sure 550's are for pre 99 classics...
