Built for performance and show utilizing the highest quality components, the K&N 77 Series High-Flow Performance Kit is a free-flowing mandrel-bent aluminum tube Cold Air Intake system designed for Trucks and Sport Utility Vehicles. 77-Series intakes have a polished aluminum finish. 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 volume 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).

K&N 77 Series High Flow Air Intake Reviews
After lifting my 2008 JK and adding larger tires, my Jeep lacked the pickup it once had. After adding the K&N High Flow Air Intake and Magnaflow Dual Exhaust, she more than had her power back and had a much nastier, strong sound.
Took about an hour to install on the 3.8L engine, but was pretty easy overall. Again, made a huge difference in giving my Jeep some power again and I highly recommend.
K&N air intake fully met all my expectations. High quality, sounds great, and easy install that took about 90 minutes.
This is a great addition to my 2009 J.K. Unlimited Rubicon. I just upgraded to 35 inch tires and wanted to get back some of the torque and horsepower I lost and this was the ticket. First off, installation was a breeze, took a little less than an hour from start to finish and the instructions are easy to follow. I didn’t do final tightening on any of the brackets until it was set in place, and it lined up perfectly with all factory mounts. Pulling the O2 sensor was a little frustrating, but was able to shimmy it out after unseating it with a small flathead screwdriver. It looks great under the hood too, shiny! I like the throaty noise it adds under hard acceleration, and it doesn’t drone under normal highway conditions. I’m extremely happy with this product, and kicking myself for not purchasing this years ago.
