The Sinister Diesel Cold Air Intake for 2019-2021 Dodge/RAM Cummins 6.7L features a precision CNC mandrel-bent aluminum intake tube, ensuring smooth, unrestricted airflow and a perfect fit. CNC machining guarantees consistently accurate bends, while mandrel-bending prevents deformation, maximizing airflow for improved throttle response, power, and long-term durability. Unlike competitors that use plastic—prone to brittleness and cracking in harsh environments like the engine bay—Sinister Diesel’s high-grade aluminum construction offers superior strength and reliability, even under extreme temperatures and conditions. This intake is engineered to enhance engine performance and provide lasting dependability for your Cummins-powered truck.
