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.

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.

Time to install was a bit off for me, but I am mechanically challenged. Did get it installed in a reasonable amount of time. It works like a charm. Perfect for our jeep.

Outstanding, just like you expect from K&N products. One very minor issue would be the ease of installation using the provided booklet. I found that watching it on youtube several time really helped.

Easy install, works as promised, intake noise is greater than stock but sounds decent.

This is a great intake, it makes a big difference in performance and I would recommend this to anybody that's looking to get a little more power out of their jeep.
