K&N 63 Series High Performance Cold Air Intake 2011-2014 Ford Mustang 5.0L

These K&N 63 Series high performance cold air intakes are truly state-of-the-art! K&N starts with the largest conical shaped high-flow air filter that they can fit into the engine compartment while using factory holes and mounting points. This extra filter size provides even more airflow at lower restriction than a standard K&N original equipment replacement filter that is limited to the size of the factory air box. The oversize air filter also captures and holds more dirt, increasing the service life before cleaning is required (up to 100,000 miles). The filter is isolated from high engine temperatures by a heat shield designed to lower the temperature of the air entering the engine, which increases horsepower. Next, K&N attaches the filter to a rotationally molded tube made from interlaced high-density polyethylene. This process gives you a precise shape for the tube to reduce turbulence and accelerate airflow into the engine.
