The K&N 71-2591 Air Intake fits some Ford F150 models. See vehicle applications link for details.
The K&N 71-2591 Blackhawk Induction Air Intake System is a free-flowing, mandrel-bent aluminum tube air intake system that is guaranteed to gain power. It replaces your Ford F150’s restrictive factory air filter and air intake housing. 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 an engraved K&N plate welded on to which gives it a clean, high-performance look under the hood. The intake tube accommodates the factory EVAP vent and crank case vent hoses. 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.

Very easy to install and made an awesome difference on my 2015 F-150 5.0. I have noticed a bit better gas mileage ... but the sound is incredible.

Price is average for these type of intakes, but still could be a little cheaper, say under $300. I'm a firm believer in you get what you pay for, this is no exception. I have used many different intakes on many different vehicles, but this Blackhawk series is amazing.The almost 12hp gain is noticeable in throttle response and in overall power. My biggest surprise was the sound. The description said increased aggressive sound.....that is not a lie. Step on the gas and you unleash the pissed off fury of aggression that has been bottled up before this intake was installed. I highly recommend this intake to all available vehicles.
