The K&N 77-1566KP Air Intake fits some Jeep Wrangler models. See vehicle applications link for details.
The K&N 77-1566KP high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Jeep Wrangler models. The restrictive factory air filter and air intake housing on your vehicle are replaced by this K&N air intake system which is designed to dramatically reduce air flow restriction as it smoothes and straightens air flow. The improved air flow allows your engine to inhale a larger amount of air than it would from the stock air intake. More air means more usable power and acceleration throughout your engine’s RPM range. The 77-1566KP air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through the intake tube into the engine’s throttle body for a guaranteed power gain. The intake tube has an attractive chrome-like finish that's made to last and it accommodates the factory air temperature sensor and a replacement silicone crank case vent hose. The oversized cone shaped 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 usually in 90 minutes or less using existing factory mounting points. The tools needed are a screwdriver, ratchet set and several wrenches. Some K&N 77 series air intakes are not legal for sale or use in California and other states adopting California emission standards while others are CARB exempt and 50 state legal. Check the K&N catalog or website for vehicle applications and specific CARB status for each vehicle and air intake.

K&N 77-1566KP Air Intake Product Reviews

Monday, February 13, 2017 - Part 77-1566KP
This is worth WAY more than the investment on my Rubicon. I also added an exhaust system & together makes one helluva difference. Don't think twice about a K&N, also have them on my lead sled & ram pickup.

Installation was a breeze. In fact it was more confusing figuring out what bolt/washer combination to use than installing the unit. First test drive we took the front tops off to really hear it purr and it sounds great. Acceleration and power were obvious. To soon to see if mileage does increase , but as long as it didn’t decrease who cares, it is a great inexpensive HP boost. My only complaint was that I was missing 3 of the flat washers in the kit. Easy fix. Ran to local hardware store and spent 50 cents for replacements... Everyone can make a mistake. I was pissed at the time until I heard it roar during the first test. My drive to work just became a lot more fun I think... I highly recommend this to anyone looking for an inexpensive HP and true power sound boost. I can't wait to pass a little Honda with the fake mufflers :)

I was looking for an improvement is power and gas mileage and that's what I got. You guys are the best at what you do. Didn't take long at all to install (77-1566KP) providing you are somewhat mechanically inclined. Might be a little challenging for someone who doesn't know their way around under the hood, but they wont have much difficulty if they just read the instructions.
Exhaust is next! Keep up the good work.
