The K&N 63-1566 Air Intake fits some Jeep Wrangler models. See vehicle applications link for details.
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.

K&N 63-1566 Air Intake Product Reviews

Couldn't be happier. Took a little over 2 hours to install but I'm a beginner when it comes to auto mechanic work. The sound is unbelievable and the immediate increase in throttle response/acceleration blew me away. The vent hose was a tight fit (which is great) but was difficult to attach. I recommend this to EVERYONE and will install a K&N intake system on every vehicle I own for the rest of my life.

Great addition to our 2014 Wrangler Unlimited. Fairly easy install with noticeable change in horsepower. Like the gutteral sound of it as well.

Made a noticeable difference in the pep and sound of the motor. I had the (Brand Name) CAI before this and it doesn't even compare.

Love the intake and performance change I got from it. Installation for the most part was pretty easy ... breather hose didn't fit well back onto the engine but thanks to the Florida temps I got it heated up and managed to get it on and cover over filter was a bit of a hassle to get screws lined up and started. I would highly recommend this to any Jeep owner ... it was like someone took their hands off the throat of my engine and let if breathe.

Installation was completed in just over two hrs. The filter was wrapped in plastic but did not state if conditioning is required. Don't think I have any improvement on fuel mileage, hard to tell if any improvement on HP, but sure sounds impressive.

Installation of tube onto intake was tricky but Youtube saved me. My Jeep sounds better, gets better gas mileage and I am very happy with my K&N air intake.
