K&N 63 Series air intakes are guaranteed to add horsepower and acceleration to most vehicles out there. These tubes allow large amounts of cool air to flow unrestricted, ensuring better combustion, adding horsepower and even bettering your fuel economy. They feature a polyethylene that resist heat-soak for the coolest air intake temperatures. K&N used the largest conical shaped air filter they can fit in the engine compartment to ensure a less restrictive air flow, allowing more air in at once. It was designed to lock out dirt dust and other debris. When dealing with a factory air intake system, there seems to be a natural restriction that occurs somewhere between the filter and your vehicles engine, but not true with the K&N 63 Series high performance air intakes. This cold air intake system eliminates air flow restriction, ensuring more power! | K&N 63 Series AirCharger Air Intake 63-3090
