Efficiently moving air into any engine is crucial to making power. Fox Lake has worked extensively to maximize the airflow in modular Ford applications. The development of the P-51 intake on top of Fox Lake's cylinder head and intake porting has proved to be a winning combination when it comes to big power. The P-51 intake is capable of providing gains of 5 to 15 hp on a naturally aspirated street car and gains as high as 75 hp over the stock intake when boost is present. Couple that with ported cylinder heads and custom cams, and Fox Lake puts extreme performance in your hands.
