Bosch injector with the 4-hole disc fuel nozzle. are they any good? or should i go stock injector?

 

By memory the stock fuel injectors only have 1 hole. The 4 hole will be better for atomization of the fuel. But on a stock engine especially on a V6 it is not needed. If you were to do a supercharger or turbo then it would help.

I say stick with stock style. Unless you are replacing yours anyways. And you get the same pressure rating injectors.
