Upper Injector EFI Location Option

Manifold with Upper Injector Location for EFI instead of the standard lower location.  Upper Injector location has been shown in testing to make slightly more power than the lower placement.  People running Direct Port Nitrous also prefer the upper injector placement as it allows for the nitrous plumbing to be kept low and out of the way of the throttle body making for a better packaged setup.  Select this option and add to you cart if you prefer upper injector locations instead of the lower injector location. Can be applied to any of the 8 injector EFI Manifold options.  Comes with Upper mounting bungs welded to the manifold and includes - 12 Fuel Rails with necessary mounting hardware.
