K&N Air Intake System 77 Series Performance F-150 2011-2014

Kickstart your performance modification journey with a K&N 77 Series Performance Air Intake System (77-2581KP). Adding the system to your 2011-2014 F-150 results in power gains and better engine acoustics.

K&N starts by replacing your restrictive factory air filter and air intake housing to seriously straighten out and improve air flow. Air travels through the intake tube and into the engine's throttle body and turbo inlet. The increased air supply leads to more power and acceleration throughout your engine's RPM range.

Features and Benefits:
- Enhances Throttle Response and Engine Sound
- Aluminum Intake Tube with Chrome-Like Finish 
- More Power Throughout the RPM Range 
- Installs Using Existing Factory Mounting Points 
- Oversized, Cone-Shaped Air Filter 
- Proudly Made in the USA! 

The intake tube features a free-flowing, mandrel-bent design with a chrome-like finish. It will accommodate the factory mass air sensor, replacement crank case vent, and EVAP check valve hoses.

The Air Intake also includes K&N's high-flow chrome air filter and heat shield. These install directly onto the lower airbox. The air filter boasts 100,000 miles of operation before servicing is needed, depending on driving conditions.
