The K&N 77 Series Cold Air Intake System is built for those who demand more power and performance from their vehicle. This precision-engineered system replaces the restrictive factory airbox with a high-flow design that increases the volume of cool, oxygen-rich air entering the engine. The result is improved horsepower, torque, and throttle response for superior performance on the road or while towing. Constructed from lightweight aluminum with a polished mirrored finish, this intake enhances both airflow and engine bay appearance. Its oversized K&N High-Flow Washable Cotton Air Filter captures impurities while maintaining unrestricted airflow for up to 100,000 miles before cleaning is needed. Each system is dyno-tested for reliable performance and sound—providing an aggressive growl under acceleration and smooth quietness at cruising speeds. Installation is simple with detailed instructions and all hardware included. Proudly made in the USA, this system is backed by K&N’s No-Hassle Lifetime Limited Warranty and designed to deliver lasting performance without voiding the factory warranty.
