Upgrade the air intake system on your 2011-2016 Ford Super Duty with the Sinister Diesel SD-CAI-6.7P-11 Cold Air Intake. Designed for Ford F-250 and F-350 trucks equipped with the 6.7L Powerstroke diesel engine, this intake helps provide a more efficient path for incoming air compared with the factory system. Improved airflow can support consistent engine performance, throttle response, and turbocharger operation under a range of driving and towing conditions.
The Sinister Diesel cold air intake is engineered specifically for the 6.7L Powerstroke platform, helping maintain proper fitment and compatibility with the original engine layout. Its application-specific design makes it a practical upgrade for daily-driven trucks, work vehicles, and towing-focused builds. The intake is intended to work with the truck’s existing engine management system while providing a streamlined replacement for the factory air intake components.
This Sinister Diesel intake is EPA compliant and carries California Air Resources Board Executive Order D-721-3. Verify vehicle application and emissions requirements before installation to ensure compliance with local regulations. Professional installation is recommended for proper routing, sealing, and operation. The SD-CAI-6.7P-11 is sold as one complete intake system for compatible Ford Powerstroke applications.
