K&N 77 Series Cold Air Intake

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.
