JLT Performance Cold Air Intake

12-21 Jeep Grand Cherokee 6.4L SRT

CAI-SRTJ-12

The JLT Performance Cold Air Intake System is precision-engineered to unlock the full potential of the 6.4L SRT engine. Its innovative design reduces intake restriction and improves airflow for noticeable gains in power, throttle response, and engine tone. Constructed from durable rotomolded plastic, the intake tube’s massive 5-inch opening ensures optimal airflow while preventing heat soak. A fully enclosed heat shield keeps intake temperatures low by drawing in cooler, denser air from the front grille area. This system features a custom S&B Powerstack cotton cleanable air filter with deep pleats and a smooth bellmouth for maximum surface area and airflow efficiency. With an OEM-like textured black finish, it not only performs exceptionally but also looks at home in the engine bay. No tuning is required for installation, offering easy performance enhancement right out of the box.
