Blackhawk Induction air intake systems feature an oil-free synthetic filter media, black powder-coated aluminum intake tube, and all-black components. The layered DRYFLOW synthetic filter provides increased airflow and exceptional engine protection without requiring oil, and a steel heat shield helps protect intake air from the high temperatures of your engine bay. The system can typically be installed in less than 90 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. K&N Blackhawk Induction cold air intake systems are guaranteed to provide an increase in horsepower and torque, and are protected by the K&N No-Hassle Lifetime Limited Warranty.
