K&N 2015 Ford F-150 5.0L street legal air intake system

The K&N 2015 Ford F-150 5.0L FIPK performance air intake system reduces restriction and increases airflow for a 50-state street legal performance upgrade

For over 30 years the Ford F-150 has been the best-selling vehicle in the United States. For 2015 the Ford F-150 was completely redesigned and is currently one of the hottest selling vehicles on the market. The beauty of the 2015 Ford F-150 is its all-aluminum body panels, as well as a new frame made of 77% high-strength steel. The aluminum and high-strength steel have helped the 2015 F-150 shed up to 750 lbs. Less weight means higher payload and towing capacities, more miles per gallon, and a better power to weight ratio.

The 2015 Ford F-150 will benefit from more street legal power from K&N air intake system

The 2015 Ford F-150 has shed up to 750 lbs. and less weight combined with more power from a street legal K&N air intake system will increase the rate of acceleration

Performance minded drivers know that less weight and more power combine to increase the rate of acceleration. K&N can help the lighter 2015 Ford F-150 with a 5.0L V8 engine with a 50-state street legal boost in horsepower and torque for improved towing performance and better acceleration. K&N got to work developing an air intake system for the 2015 Ford F150 5.0L V8 and obtaining an Exemption Order (EO) from the California Air Resources Board (CARB) making this intake available for sale and use in California as well as other states with similar emissions standards.

An air intake system, like one from K&N, is designed to increase power by significantly reducing air intake tract restriction and increasing the amount of air available to the engine. K&N does this by replacing the 2015 Ford F150 5.0L V8 engine’s stock air filter box with an open oversized K&N high-flow air filter, and eliminating the accordion flex hose stock air intake system with a smooth walled and molded K&N air intake tube. Reducing the amount of power wasted on drawing air into the engine can translate into more power where it counts; at the wheels.
