The K&N 77-1566KP Air Intake fits some Jeep Wrangler, and Jeep Wrangler JK 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

Sunday, April 15, 2018 - Part 77-1566KP
This is my second purchase of a K&N air intake system. My 1st was on my 2004 Dodge 2500 Truck. Install on my Jeep took about 2 hours as I like to move slow when removing and installing parts. In addition, watching the videos on removal and installation makes reading the instructions much more user friendly. Must use metric sockets as recommended. The response was immediate when hitting the accelerator. As of right now, it looks like I have gained .05 MPG but only have it installed for a month. The sound on my truck was much louder so slightly disappointed the rumble is not the same as on my Jeep. In addition, my engine compartment has more room to move around in now the factory intake system is off. Great product.

Super pleased. Installation instructions were detailed with photos. Install was a breeze with very few tools required. Gained some extra sound under the hood and picked up 1-2 mpg as well. I would definitely recommend the air filter shield if you bought this for a Jeep and do any off roading. Your Jeep won’t be a submarine with this set up either. Throttle response is a little better too. I would recommend this to jeep buyers that don’t get in to water all that much.
