JLT Performance Cold Air Intake

11-24 Dodge Durango / Jeep Grand Cherokee 5.7L Hemi

CAI-DJ57-11

The JLT Performance Cold Air Intake is precision-engineered to enhance the performance of 5.7L HEMI engines by significantly reducing air restriction and improving flow over stock systems. Built from durable rotomolded plastic, the large-diameter intake tube ensures smooth, unrestricted airflow while preventing heat soak—unlike metal tubes. A custom S&B Powerstack air filter with deep pleats and a 5” opening maximizes surface area for exceptional filtration and increased horsepower. The included ABS heat shield isolates the intake from engine heat and seals tightly to the hood, drawing cool air from the factory grille inlet. The result is improved throttle response, enhanced induction sound, and dyno-proven gains of 8–12 RWHP and RWTQ. The black textured finish provides an OEM-style appearance, and the complete kit includes all mounting hardware plus a rain guard for models equipped with functional hood vents. No tuning is required for installation.
