I have a set of SRT4 injectors 4 sale because i cant use them with my setup. According to the internet these are stage 2 injectors (Part # P4510529) Complete set of 4, asking $180. i got them used, the previous owner said they were only for about 500 miles before swaping them out for bigger ones. They are in perfect working condition because i personally know the guy i got them from. PM me if ur interested.
