12-25 Dodge Durango / Jeep Grand Cherokee 6.4L SRT 392
77-1567KS
The K&N 77 Series Cold Air Intake System is engineered to take your 6.4L SRT 392 engine’s performance to the next level. Featuring a precision mandrel-bent aluminum intake tube, it provides a smooth and unrestricted airflow path, dramatically improving throttle response, horsepower, and torque. Dyno-tested to deliver an estimated gain of 27.86 HP and 30 lb-ft of torque, this system ensures noticeable performance enhancement across the RPM range. A signature K&N High-Flow™ oiled cotton gauze air filter sits at the heart of the system—washable, reusable, and built to provide superior filtration without sacrificing airflow. The oversized conical design extends filter life, requiring service only every 100,000 miles under normal driving conditions. The intake also replaces the factory airbox and intake tubing, reducing restriction and heat soak. The durable silver powder-coated aluminum tube not only performs but also adds a clean, performance-oriented look under the hood. Installation is simple and can typically be completed in about 60 minutes using standard hand tools. Backed by K&N’s No-Hassle Lifetime Limited Warranty, the 77 Series Cold Air Intake is built to last and engineered to perform.
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!
