The Sinister Diesel Cold Air Intake for the 6.7L Cummins turbo diesel engine (2007.5-2012) is engineered to optimize your truck’s performance. Designed to enhance throttle response and turbo spool-up, this intake system ensures your engine runs more efficiently, making it perfect for daily driving, towing, and even racing applications.
This intake retains your factory air intake boot and features precision CNC mandrel-bent aluminum tubing for smooth airflow and durability. The oversized reusable cotton filter provides maximum filtration and airflow while reducing the need for replacements. Polished and powder-coated in Signature Sinister Blue, this intake combines superior performance with standout style under the hood.
