The K&N 71-2581 Air Intake fits some Ford F150 models. See vehicle applications link for details.
The K&N 71-2581 Blackhawk Induction Air Intake System is a free-flowing, mandrel-bent aluminum tube air intake system that is guaranteed to gain power. It replaces the restrictive factory air filter and air intake housing on some Ford F150 models. This low restriction air intake allows your engine to inhale a larger amount of air than it would from the stock air intake. More air means more power and acceleration. This K&N Blackhawk Induction Air Intake System comes with black components including the K&N high-flow air filter and heat shield. The attractive textured black powder-coated tube features a welded, engraved K&N plate giving you a clean, high-performance look under the hood. The intake tube accommodates the factory mass air sensor, EVAP hose and crank case vent hose. The oversized cone shaped air filter is made from an oil-free synthetic filter media that can be used for up to 100,000 miles before cleaning is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using the existing factory mounting points using commonly available tools. Some K&N Blackhawk Induction Systems are not legal for sale or use in California and other states adopting California emission standards while others are 50 state legal. View the 71-2581 vehicle applications to determine the legal status for each vehicle.

K&N 71-2581 Air Intake Product Reviews

Monday, August 21, 2017 - Part 71-2581
Received it really fast. Took about 30 mins to install. It made a huge difference in the sound. I really can't tell about the fuel mileage yet cause I keep putting my foot into it, cause the way it sounds.

Great service and prompt shipping. The product was everything advertised and installed easily. Truck sounds and runs great with the new filter.
