Improve airflow, throttle response, and turbo spool-up with the Sinister Diesel SD-CAI-6.7C-13 Cold Air Intake, designed for 2013-2018 Dodge Ram 2500 and 3500 trucks equipped with the 6.7L Cummins diesel engine. Engineered and fabricated in-house, this intake uses precision CNC mandrel-bent aluminum tubing for strength, durability, and a consistent fit. The system retains active air technology to help prevent diagnostic codes and is designed as a direct replacement for the factory intake system. This application will not fit 2019 or newer models.
The Sinister Diesel intake includes an oversized, reusable cotton media air filter that supports improved airflow while providing long-lasting service. Silicone couplers offer greater reliability than typical original-equipment materials, while the polished and powder-coated Sinister Blue finish adds durable protection and a distinctive appearance. Whether used for daily driving, towing, or performance applications, the intake is designed to provide dependable operation and improved engine response. It can also complement a Sinister Diesel exhaust system or tuner.
Installation is straightforward with the included CNC mandrel-bent aluminum intake tube, reusable cotton media filter, installation hardware, and instructions. The kit is designed for drop-in installation using common hand tools and minimal mechanical experience. For additional filtration in dusty or demanding environments, check the manufacturer’s website for an available pre-filter. The aluminum tube is thin-walled to promote rapid heat dissipation as airflow moves through the intake, helping reduce heat soak compared with materials that retain heat longer.
