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). This 77 Series Air Intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards. Check the K&N catalog or website vehicle parts search for specific CARB status.

 Good Buy. Easy Installation, as adding stuff like this should be! Love the feel of the extra power and the sound of the extra ponies on our 2014 Ford Explorer.
Tony Garcia, Raleigh North Carolina
 So far, very pleased. I installed the unit yesterday and drove in to work early this morning. There was a definite improvement in throttle response. The delay was gone. I think that pick up increased but that was hard to tell as I had the ac off and windows open and typically I have the ac on. I will say this, incredible sound. Under normal driving, you don't hear anything different but if you punch it, you will hear a woof of that air coming in and it sounds impressive!

 Noted 3 MPG pickup as well as increased throttle response.
