The K&N 77 Series Cold Air Intake System is engineered to enhance engine performance by delivering cooler, denser air to your engine for a guaranteed boost in horsepower and torque. Its precision mandrel-bent aluminum intake tube minimizes restriction and increases airflow, while the oversized oiled cotton High-Flow Air Filter™ captures harmful contaminants for superior engine protection. Designed to replace the restrictive factory air intake, this system improves throttle response, engine sound, and overall driving performance. The filter only requires cleaning every 100,000 miles under normal highway conditions, making it a long-lasting, cost-effective upgrade. Installation is simple and can typically be completed in under an hour with basic tools. Backed by K&N’s No-Hassle Lifetime Limited Warranty, this system ensures reliable performance without voiding your vehicle’s factory warranty.
