I may have the 440 injectors for you. I have to track them down in my garage, but i know i didnt sell them yet. They are KGparts injectors. no resistor box needed. paid 250 for them new. They have about 1500 miles on them. Ill do 100 for them. U may need o rings, im not sure if they have them. Ill pm you later after i look for them.
