I was looking up injectors for my LS and i was wondering what the difference of the nozzle style (disc) and nozzle style (Ball and Seat). I want the Precision 440cc Honda Style Injector (Top Feed) because they are plug and play so to speak. I wouldnt have to do any re-wiring from what i hear. Now...these are disc nozzle style....whats the difference between the two?
