Xcessive's Top Fueler for the Mazda Speed 2.3 DISI motor allows you to add 4 more top feed Bosch style injectors (14mm o-ring) to your motor by simply bolting this plate between the manifold and head and wiring a piggy back injector driver. Ran out of fuel on your stock injectors? This will fix it.
The rails are threaded both ends for 3/8 NPT hose barbs or NPT to -AN for easy hook up.
