Product Overview
The Sinister Diesel Cold Air Intake for the 2013–2018 6.7L Cummins delivers a noticeable upgrade in airflow, turbo response, and engine sound compared to the restrictive factory intake system. By replacing the narrow, plastic factory tube with a smooth, mandrel-bent aluminum design and a large high-flow filter, this system lets your turbo breathe easier—improving both performance and efficiency.
Expect quicker throttle response, faster turbo spool, and an aggressive intake tone that makes your turbo whistle and exhaust brake come alive. Whether you’re towing, hauling, or just driving daily, the difference in throttle feel and power delivery is immediately noticeable.
Each intake is designed to integrate perfectly with your truck’s factory components, retaining the Active Air system and all OEM sensors to prevent any check engine lights. Finished in our signature Sinister Blue powder coat, this intake doesn’t just perform—it transforms your engine bay with a clean, custom look built to last.
