The K&N Cold Air Intake System is built for long-lasting performance and protection, backed by a 10-Year/Million Mile Limited Warranty. Designed to deliver a guaranteed increase in horsepower and torque, it has been dyno-tested to provide up to 50% more airflow than restrictive factory air intake systems. This added airflow improves throttle response, making it ideal for better towing performance and uphill acceleration, while also enhancing your vehicle's engine sound for a more aggressive tone. The included high-flow air filter offers world-class protection against harmful contaminants and requires no cleaning for up to 100,000 miles. With a simple bolt-on design, installation can be completed in less than an hour using basic hand tools and requires no ECU tuning, making it one of the easiest and most effective upgrades for your vehicle.
