I have a 3.9 magnum in my 99 Dakota sport 5 speed I was wondering if anyone has swapped the stock injectors with bigger ones I was thinking about using the 4.7 magnum injectors cause there bigger. Any and all recommended injectors to use be much helpful

 

Moved to the correct section. Swapping injectors alone will do nothing without supporting mods. What are you trying to accomplish?

 

If anything, swapping injectors can cause a whole lot of issues not just with the fuel system...
