New 50-State Legal Intakes for Many Silverados, Colorados, Sierras, and More

K&N® has recently received an executive order from the California Air Resource Board approving multiple cold air intake systems for use in California. These 50-state legal intakes are now offered for the applications listed below, including many Chevrolet Colorado, Chevrolet Silverado, GMC Canyon, GMC Sierra, and Cadillac ATS models (among others).

Please view the individual product pages for the most up-to-date information on vehicle applications and legal status.

K&N performance air intake systems are designed to create a more aerodynamic path for airflow to reach the engine by removing the stock intake tubing that can create excess turbulence, and also by utilizing highly airflow-efficient filter media.

In a K&N cold air intake system, air first passes through a performance air filter—typically a High-Flow Air Filter™, which features an oiled, layered cotton media—and then passes through an aerodynamically-engineered tubing system that helps prevent unnecessary turbulence/heat.

Cold air is more dense than warm air because it contains additional oxygen molecules—allowing the cylinders to facilitate combustion more efficiently. A factory air intake typically feeds warm air to the cylinders, while K&N performance air intake systems are designed to provide a smooth, unimpeded path for the airstream—keeping the airstream cooler and more oxygen-dense. With a K&N performance air intake system, you get a guaranteed increase in horsepower and torque.

All K&N performance air intake systems are designed to increase airflow through an aerodynamic path that reduces turbulence, and filter designs that provide an increase in the volume of air that reaches your engine. K&N offers several options to cater to different aesthetic, ease of maintenance, and filter media preferences.

Mandrel-bent aluminum intake tubes help provide an increase in airflow to your engine and reduce turbulence—keeping air cooler and providing more power. These systems are paired with a washable, reusable High-Flow Air Filter™ featuring oiled cotton filter media, and the oversized, conical design allows you to go up to 100,000 miles between filter services under normal highway driving conditions. A steel heat shield helps protect intake air from the high temperature of your engine bay, helping to increase combustion efficiency.

High-density polyethylene (HDPE) rotationally molded tubes help accelerate airflow to your engine and reduce turbulence—keeping air cooler and providing more power. These systems are paired with a washable, reusable High-Flow Air Filter™ featuring oiled cotton filter media, and the oversized, conical design allows you to go up to 100,000 miles between filter services under normal highway driving conditions. High-density polyethylene (HDPE) has a very high strength-to-density ratio, as well as the ability to withstand extremely high temperatures—making it an excellent choice for the environment in the engine bay. HDPE can also be molded into custom shapes, allowing it to be adapted for specialized tubing designs. A steel heat shield helps protect intake air from the high temperature of your engine bay, which helps increase combustion efficiency.

Blackhawk Induction air intake systems feature an oil-free synthetic filtration media, black powder-coated aluminum, and all-black components. The layered DRYFLOW® synthetic filtration media provides increased airflow and exceptional engine protection without requiring oil, and a steel heat shield helps protect intake air from the high temperature of your engine bay. Service your filter every 100,000 miles under normal highway driving conditions.
