The K&N DRYFLOW Air Intake System replaces your vehicles restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicles engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engines RPM range. The DRYFLOW Air Intake System features an oil-free synthetic filter media providing increased airflow and exceptional engine protection without requiring oil. This allows cooler, denser air to be directed through a custom intake tube into the engines throttle body for a guaranteed power gain. The system can typically be installed in less than 60 minutes. Some intakes are not legal for sale or use on any pollution controlled motor vehicle in California. See the product specifications for CARB status on each part for a specific vehicle.
