Fuel Injector leakin!

[Z3Px]

yea so i found out 2 of my fuel injectors were leaking yesterday. Not terribly, just enough to where i could see a performance loss and danger. Anyway, this will be the first time i will be replacing them since i have owned the car, and i was wondering what are the best bang for the buck here, i know i can get venoms at around 80 bucks a piece, but i was looking for something around 150 for a set of 4. And should i see a significant increase in performance after i change them out, especially since it feals like it doesnt really accelerate when i put the pedal to the metal. Allrighty, thanks alot in advanced (yes i did search)

is it the actual INJECTOR leaking? It could just be a bad O-ring...which are no big deal.
