This video compares the spray pattern of the stock OEM Siemens Deka Fuel Injectors 53030778 used in 4.0L Jeeps to a Bosch 0280155703 Fuel Injector. Notice the Bosch injector has a much wider spray and how much better it atomizes the fuel. Upgrading to these Bosch injectors will increase overall performace and throttle response.
