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.

 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!

 Great quality and great fit. Seems to perform well. Only complaint is that I had to keep referring to schematic to determine which hardware to use. Should refer to the parts for each step of installation.
