JLT Performance Cold Air Intake

18-26 Dodge Durango 6.4L SRT

CAI-DD64-18

The JLT Performance Cold Air Intake System for the 6.4L SRT engine is built to unleash the full potential of your powerhouse SUV. Dyno-proven to deliver gains of 18–22 rear-wheel horsepower and torque, this system outflows the factory intake with a massive 5” inlet tube and precision-engineered airflow path that eliminates restrictions and bends. Constructed from durable roto-molded plastic, the intake tube resists heat soak and provides a smooth, consistent flow of cool air. The custom S&B Powerstack air filter, featuring deep 1" pleats and 75 grams of red oil, offers superior filtration and increased surface area for maximum airflow. A fully enclosed heat shield seals to the hood and draws fresh air directly from the grille and bumper area, keeping intake temperatures low and performance high. This intake system installs easily, requires no tuning, and enhances both power and the aggressive tone of the 6.4L HEMI engine—making it a perfect upgrade for drivers who demand more performance, sound, and style from their vehicle.
