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.
