You should consider an intake/filter. You want to upgrade to a larger cone filter f ok r the surface area of the filter, as the OE filter is undersized and already chokes the engine of air. You can get an enclosed filter box, lots make them (e.g. S&B, etc), which will not increase noise, but will allow for increased air flow. Keep in mind, the OE filter in the Raptor shares the same filter as the standard Ecoboost...more horsepower and torque needs more fuel and air!
