The K&N AirCharger 63-1566 air intake system replaces the restrictive factory air filter and air intake housing in some Jeep Wrangler models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your Wrangler’s engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 63-1566 air intake comes with a chrome topped K&N high-flow air filter and a K&N embossed heat shield that mounts into the lower air box to act as a cover allowing cooler, denser air to be directed through a custom molded intake tube into the engine’s throttle body for a guaranteed power gain. The oversized air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install requiring only a screwdriver, a socket set and several wrenches. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

Product Reviews


  This is the third vehicle on which I have installed one of these intakes and I am again enormously pleased. Installation is pretty easy, with only one minor problem with the length of the provided crankcase breather hose (slightly short, very stiff). The solution was easily improvised, improved performance was immediate, and continued to improve after being driven for a few weeks. I would highly recommend this to anyone with a new Jeep. Original engine performance was OK, but anemic compared to the old straight 6. With the K&N intake, acceleration is improved significantly, and I can now use 5th and 6th gear much more often, even on slight grades, which was not possible before. Great product.

  I spent about 90 minutes installing the new performance intake kit on my 2014 Unlimited Dragon. The instructions were straight forward and everything went together perfectly. The toughest part for me was removing the intake air temperature sensor from the factory inlet tube. I didn't want to damage or destroy the sensor, so I took my time. It just took a little brute force to pull the sensor and o-ring out of the tube. The rubber hose connection for the crankcase vent tube at the engine was a very tight fit, but it doesn't require a clamp. I didn't notice any change in the tone or volume of the engine intake noise at idle or at cruising speed. If anything, the air intake noise seemed to be a little quieter. As soon as I made a couple 3/4 throttle accelerations I could immediately feel and hear the change in the engine. At full throttle the change was fantastic. I had flashbacks to the sounds of the back 2 barrels of a quadrajet carb kicking in. The engine revved up so quickly that the RPM limiter kicked in before I could let off the pedal. With the addition of my cat-back dual exhaust and the K&N Performance Intake kit, my ride now sounds and feels like a new machine.

  Works as claimed. Added horsepower as claimed. Install was as easy as claimed. Did exactly what was claimed. Not much to say, but GREAT JOB! Thanks for making claims that you backed up 100%!

  Great Product, takes approximately 40 minutes to install including taking your old system off. No special tools needed. Good looking system and noticeable power gains. Really wakes up the bottom end and also smooths out the top end. Good job to the guys at K&N this product works. Inexpensive way to gain a few ponies & torque.

  The shipping was quick. The installation was clean and straight forward. The intake provides a cool sound to my Jeep.

  Fairly quick and easy to install. Watch the sensor. It takes some work, but it will come out of the old air intake and install in the new one. It is a little noisy under hard acceleration, but not bad. I feel a little more power with this as opposed to the original intake and filter.

  Everything that I expected from K&N. Took approximately 2 hours to install, with the removal of the old breather. Great sound, improved throttle response, and easy install. Haven't noticed mileage increase up to this point, but only had it on for about one week. This is the second intake kit I have installed by K&N and will continue to install your products. I will be installing your replacement air filter on my motorcycle, which I also purchased at the same time as this system. Thanks!
