Look guys I have already paid the 600 core charge on these injectors and I can collect it back by sending them in if everybody thinks they are only worth a couple hundred. The truck had occasional hard warm starts and was running a good fuel system for a LONG time so Im not going to give them away. I can send them in for upgrades myself and have a cheap set around to sell for retail later. Im sorry if you only have a few hundred bucks to spend. I may take trades for 12V performance stuff as well. Ive got 2 sets here to choose from also before they go back.
