The Sinister Diesel Cold Air Intake is an ideal upgrade for enthusiasts seeking a balance of power, reliability, and ease of installation.
Key Features
This intake system combines precision engineering with high-quality materials to deliver superior performance and durability. Key features include:
- Precision CNC mandrel bent aluminum tubing for a perfect, smooth airflow path and a precise fit
- Oversized, long-lasting reusable cotton media filter that maximizes air filtration and flow
- Maintains active air technology to prevent check engine codes and ensure proper sensor function
- Significantly improved throttle response and faster turbo spool-up for enhanced driving dynamics
- Durable silicone couplers that outperform OEM materials in reliability and longevity
- Available in polished aluminum or powder coated in Sinister Diesel’s signature Sinister Blue finish
- Easy drop-in installation requiring only basic hand tools and minimal mechanical experience
- Designed to complement Sinister Diesel exhaust systems and tuners for maximum performance gains
Construction & Design
The intake tube is crafted from CNC mandrel bent aluminum, ensuring smooth bends that optimize airflow while maintaining structural integrity. This manufacturing process eliminates restrictions caused by sharp bends or weld inconsistencies common in lesser designs. The aluminum tubing is available polished for a sleek look or powder coated in Sinister Blue, providing a durable finish that resists corrosion and wear.
The included reusable cotton media filter is engineered to provide superior filtration while allowing increased airflow compared to stock paper filters. Silicone couplers used in the kit are designed to withstand high temperatures and pressures, offering a more reliable seal than OEM rubber components.
Performance & Sound
By increasing the volume and quality of air entering the engine, the Sinister Diesel Cold Air Intake enhances throttle response and turbocharger spool-up times. This translates to quicker acceleration and improved engine efficiency under load. While the intake primarily focuses on performance gains, it also contributes to a subtle, more aggressive induction sound that adds to the driving experience without excessive noise.
Installation & Fitment
The Sinister Diesel Cold Air Intake is designed as a direct replacement for the factory intake system on 2013–2019 Ram 2500 and 3500 trucks with the 6.7L Cummins engine. Installation is straightforward and can be completed with common hand tools in under an hour. The kit includes all necessary hardware and detailed instructions, making it accessible for enthusiasts with minimal mechanical experience. No modifications or additional tuning are required to retain factory sensor functions and avoid error codes.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
