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

Tuesday, December 5, 2017 - Part 77-1566KP
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.

Instructions are vague, need to look at exploded view diagram to actually understand how it's installed. Nice performance increase. Appears to be minor increase in MPG. Slightly louder during acceleration. Sounds like it should.

Fit and finish are perfect. Very noticeable improvement on throttle response and fuel economy. Plus it sounds cool.

Easy install. Can feel the difference (big) in pickup and throttle response. I like it. Only issue was the hose for the crank case exhaust was 1/2, which was okay fitting to the intake tube. But the crank case line was larger and the 1/2 hose provided was not going to get over it. Had to improvise. No leaks. Working fine now and roars upon request.

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.
