The Ford intake system is fantastic, absolutely the best that has ever come from the factory. It will actually keep air charge temps slightly cooler under some conditions than an aftermarket cold air. Where the aftermarket cold air shines is in airflow to support higher horsepower.
On the dyno we typically see 9 to 12 horsepower over the stock airbox, mostly above 4,000rpm. A drop in filter is not going to give you any real measureable horsepower.
Ford raised the base HP number in '13 to 420. Because of that, you will only get about 30 with our Steeda Custom Tune & CAI.
