A set of the new and improved injectors, I've been reading up on the injector issues and would like to avoid that issue all together if possible. Auto Zone has a Gp Sorenson injector part#800-1060N listed at $77 a piece, while O'Reilly's has a Motorcraft Multi Port injector part#CM5071, they don't have a price provided, but the injectors for an 04 heritage are listed at 107 each, so I imagine they would be about the same. I hope the cheaper ones would work, at least until I could afford a good aftermarket set anyways.
