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.
K&N is one of the most recognized names in performance filtration, offering reusable high-flow air filters, cold air intakes, and related filters for street and motorsports use. Their products are designed to improve airflow and serviceability—ideal for enthusiasts who want performance-oriented filtration and easy maintenance.
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
