An internal combustion engine makes power by detonating gasoline inside the cylinders. This explosion forces the piston down, turning the crankshaft, and ultimately the wheels. In order to make the fuel burn, air has to be injected into the cylinders. This catalyst is piped to the throttle body through the stock air intake system, which collects it from outside the vehicle. The problem is, the factory intake on your 2011-2014 Jeep Compass & Patriot 2.0/2.4L engines is very narrow and full of tight bends. When the outside air makes it past the thick paper air filter, it has to squeeze through the tiny intake tube and around those tight turns, causing it to slow down and become turbulent. By the time it reaches the cylinders, this hot, swirling air won't be potent enough to fully burn all of the fuel. To increase the horsepower in your little Jeep Patroit and Jeep Compass, you need to replace that warm air with oxygen-rich cold air. The additional oxygen molecules will create a more powerful explosion, which enables the engine to extract more energy/horsepower, from the same amount of fuel.
To get cold air into the engine, the K&N 57-1567 performance intake system ditches the restrictive factory air box and filter for a K&N performance air filter, which is protected from hot engine air by a rugged heat shield. The reusable air filter is made from a special cotton gauze material that provides superior filtration, and the ability to go up to 100,000 miles before it needs to be cleaned (depending on road conditions). It can also feed cooler air into the system, which then gets routed to the engine through a wide-diameter polyethylene intake tube that's been roto-molded to reduce air turbulence and restrictions. This K&N intake tube has integrated fittings for the factory air temperature sensor and crank case vent hose, enabling an install that is usually around 90-minutes. The 57-1567 cold air intake is also street legal in all 50 states. To avoid problems at the inspection station, each system is issued an Exemption Order (EO) number by the California Air Resources Board (CARB), along with an underhood decal to validate its compliance with state laws.
To validate the performance gains, we installed a K&N 57-1567 FIPK cold air intake system on a stock 2012 Jeep Patriot 2.0L and dyno testing revealed an estimated increase of 6.35 horsepower and 5.25 ft-lb of torque. That will provide a noticeable difference when you hit the gas, where the additional airflow will sharpen the throttle response.
