K&N Air Intake Systems

77 Series High-Flow Performance Air Intake Kit by K&N®. This intake kit is designed for the larger engines typically found in trucks and SUVs. It replaces the factory air intake system with a free flowing K&N air filter and custom designed air intake tube. Extensive dyno testing improved intake airflow and allows these big engines to develop even more torque and horsepower. The end result is better acceleration you can feel.

K&N - F.A.Q.K&N - WarrantyK&N - About


  • Guaranteed to increase horsepower

  • Free-flowing aluminum tube
  • Replaces entire factory air intake system
  • Lasts up to 100,000 miles before service is required (depending on driving conditions)
  • Easy to install, usually in 90 minutes or less
  • Washable and reusable lifetime air filter
  • K&N Million Mile Limited Warranty

The big "deep breathing" engine in your truck or SUV needs a 77 Series High-Flow Performance Air Intake Kit to unleash all of its power. The kit starts with an oversized conical high-flow K&N air filter, installed in place of the restrictive factory airbox. The large increase in filter area over the stock airbox filter results in a huge increase in airflow and a greater capacity to capture and hold dirt.

The increased airflow continues with a free-flowing mandrel-bent aluminum intake tube in place of the factory air path. The intake tube is available in several finishes. Most kits also include a heat shield that seals against the hood and isolates the filter from engine heat. The reduction in air intake temperature results in a cooler, denser air intake charge and even more horsepower. All components are mounted and connected with high quality materials such as steel, aluminum, silicon or reinforced nylon, to ensure long life.

K&N uses a dynamometer to design its air intake kits to make the most horsepower possible. But their power figures aren't based on just one vehicle, but rather an average of runs by a number of vehicles. This means repeatable numbers and horsepower claims you can count on.

Every 77 Series High-Flow Performance Air Intake Kit comes complete with everything necessary for installation, including comprehensive installation instructions. The K&N filter can go up to 100,000 miles before cleaning is required. And the K&N air filter is guaranteed for one million miles.

K&N® is the inventor and leading innovator of reusable cotton gauze filter technology for automotive applications. The first K&N filter was conceived for racing over 40 years ago and a performance enthusiast mindset continues today throughout all levels of the company. K&N is the sales and brand leader for performance filters, including an extensive line of factory replacement filters and performance air intake kits. The company actively promotes the environmental, economical and performance advantages of long-life reusable cotton gauze filters.

Warranty Information

K&N O/E Replacement Air Filters and Air Intake Systems purchased from Authorized Dealers are backed by a Million Mile Limited Warranty when used primarily on paved roads and on vehicles for which they were designed. If one of these products ever fails to provide complete satisfaction, K&N will replace it.

K&N Aftermarket Air Filters should be cleaned every 50,000 miles for normal highway use, more often in dusty conditions. Cleaning should be done with K&N cleaner and air filter oil (or comparable air filter cleaner and oil). Use of compressed air, or chemicals not specifically designed to clean and re-oil cotton air filters (i.e. gasoline, transmission fluid, motor oil, lightweight oil, or diesel fuel) will void the warranty. Any damaged, abused or modified K&N Air Filters will not be warranted.

Any K&N product returned to K&N will need a Return Goods Authorization number and must be sent at customers' expense along with proof of purchase.

Any defective K&N Air Filter properly returned to K&N will be replaced. K&N reserves the right to determine whether the terms of the warranty, set out above, have been properly complied with. In the event that the terms are not complied with, K&N shall be under no obligation to honor this warranty. K&N will not be responsible for any indirect, consequential, special, contingent, or other damages.

K&N wants to make sure that when you buy a K&N Lifetime Air Filter or Air Intake System, you can be confident your vehicle's warranty will not be impacted. K&N also want you to feel confident that even if you experience difficulties with a dealership repair department, K&N will step-in and resolve the issue, so you won't have to. Therefore, K&N makes the following Pledge: K&N pledges to their customers that they will not be taken advantage of and charged for a repair due to a manufacturer warranty denial blamed on the presence of a K&N product.

Magnuson-Moss Warranty Act:
Legally, a vehicle manufacturer cannot void the warranty on a vehicle due to an aftermarket part unless they can prove that the aftermarket part caused or contributed to the failure in the vehicle (per the Magnuson Moss Warranty Act (15 U.S.C. 2302(C)) Learn More

The K&N Cold Air Intake
The product is amazing. Looks great, installation was quick and easy very simple directions for those who need them and the performance of this product is to me non-comparable to any other. I feel it is the better intake system out of others and K&N products are made to last and give great results. They know how to satisfy their customers.

Nice Sound With A Little MPG Boost
I've had this product now for a month and I've done about 1100 miles with this air intake on. My Jeep was averaging around 14mpg. Now I'm getting a little over 16mpg with this air intake. Also the air intake makes the Jeep a little more responsive when I push the throttle. K&N's cold air intakes are always put on all my vehicles. It's helps the car breath boosts mpg a little and adds a little more power! When I lift up the hood it's a pretty thing to look at as well ;)

2016 Silverado 5.3l Flex.
Great product, instantly saw a little better fuel economy - when I'm not getting on it that is, and noticeably more power when I am. Plus has a nice growl the front side of the engine. Easy install, and fast shipping from CARiD. Thanks!

Another Fine K&N Install.
They seem to get easier to install every time. 30 min (for me) to install on my 2012 Silverado, 6.0L. You must use three things in front of you engine. 1. Air intake! 2. Jet chip. 3. Throttle body spacer / riser.
