Re: Will gt500 fuel injectors fit 06 4.0?
Unless you are going forced induction, bigger injectors are a waste for you. The stock injectors are designed to flow properly. You only need bigger injectors if you have forced induction and need the increased flow. The bigger injectors on an otherwise stock engine are a recipe for problems.
And I think that the GT500 injector is a different height - but not sure. So that may cause some clearance problems. I know that my car I just sold with the Xcharger had 39 lb injectors and they were not GT500 injectors (which I believe are bigger than 39 lbs.)
