Built for performance and show utilizing the highest quality components, the K&N 77 Series High-Flow Performance Air Intake is a free-flowing mandrel-bent aluminum tube induction system designed for Trucks and Sport Utility Vehicles. 77-Series air intakes come with K&N's Million Mile Limited Warranty. K&N intake systems replace your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle's engine to inhale a larger amount of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The filters on these kits are washable and reusable. Most of our intake kits are relatively easy to install using tools commonly available (see installation instructions). Some 77 Series Air Intakes are not legal for use in California and other states adopting California emission standards while others are CARB exempt and 50 state legal. Check the K&N catalog or website vehicle parts search for specific CARB status. [MORE]

Easy install. Great upgrade to my 2014 Ford F150 Raptor.

I had to share this with you guys at K&N,,I have been asking a lot of my friends about this filter system and there was a lot of doubts in people's heads if this was a sure thing,,,well let me tell you, I bought the best one chrome tube system and my throttle response is a lot better. My gas mileage has increased 30 to 40 per cent more. If I kick it at 30 ,,it spins the tires. 1997 Ford f150 with a 4.6. This has to be the best unit I could have put on my truck. It took all of one hour to put on and I could have done it quicker but I like putting it back as close to the original as possible. It sounds like a deep throat with no bottom to it. I love it and will recommend this to all of my friends from now on,,really bad ass set up. At 60 years old I feel like a reborn gear head again. You know what they say,, You are only old as you feel,,21 again,,,

I have been using K&N filters since about 1968 starting with my dirt bikes.  Use on all my vehs since.  I have a 1995 Ford F150 with a 302 and a 1997 Jeep Grand Cher with a 4.0 and both have K&N air filters.
