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. [MORE]

Great stuff, great price. My first kit lasted about 15 applications which is less than a buck per time. Just apply the cleaner and rinse off. Let the filter dry and spray on the oil and you're done. Easier than driving to the store to get another air filter which I will never do again. Can only imagine how much money I've saved never having to buy another air filter over the years. Not to mention the increased air flow, which you can literally feel when you install for the first time, which increases performance. Over 128,000 miles and counting. My K&N filter is helping my Ford Ranger get to my goal of 200,000. Thanks guys.

I installed the product as shown and immediately noticed a huge improvement. The product works great and is simple to install. I have used your products in the past and they do exactly as shown. It is so great to buy a product, install it and it actually performs like the advertisement. I would say that the video on YouTube did make it super easy to install. I have recommended the product to several of my Ford friends and they are purchasing the product as well. Thank you again.

Excellent service from K&N and excellent fit in my 2014 Ford 2.0L Escape. I run without the cap and have seen a consistent 0.5 MPG improvement along with better throttle response.
