Product Description
The Sinister Diesel Cold Air Intake for 2013–2018 Dodge Ram 6.7L Cummins delivers airflow, performance, and sound that the stock intake can’t match. The factory system is restrictive, holding back turbo response and efficiency. Our intake fixes that with CNC mandrel-bent aluminum tubing and an oversized high-flow filter, available in washable or dry media.
The result is quicker throttle response, faster turbo spool, improved efficiency—and a sound that transforms the driving experience. With this intake, you’ll really hear that signature Cummins turbo whistle and the exhaust brake roar.
Engineered to integrate seamlessly, this intake retains your truck’s Active Air technology, eliminating error codes and keeping sensors working correctly. Finished in signature Sinister Blue powder coat, it’s built for durability, corrosion resistance, and a bold under-hood look.
