The K&N 77-1559KP high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Jeep Liberty 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 77-1559KP 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 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 requiring commonly available tools to do the job. 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.

Review part 77-1559KP
Monday, July 20, 2015 - Part 77-1559KP
Saw this product on a friend's Jeep Liberty. He couldn't say enough about it. More power, greater acceleration and better gas mileage. And the sound it makes when you kick it down. Took his word and ordered one. Took 90 minutes to install. Just like it says. Unbelievable Checked under the hood to make sure someone hadn't exchanged my six for an eight. The power, the sound, just like he described. Definitely worth the price. One last thought: your gas mileage will improve, unless you keep putting the pedal to the medal like I do. Oh that sound Happy Motoring.
