The GMC Sierra 2500 Performance Air Intake from Sinister Diesel is an exceptional cold air intake designed specifically for the `11-`12 6.6L LML models, finished in the striking Sinister Blue hue. This cold air intake maximizes airflow to your Duramax engine, resulting in improved throttle response and turbo spool-up—ideal for daily driving, towing, or even racing applications.

The Sinister Diesel Cold Air Intake is engineered with precision to ensure optimal performance and quality. Constructed with aluminum tubing, the intake minimizes heat soak while maintaining smooth airflow due to CNC mandrel bending. Its oversized, reusable cotton filter media maximizes airflow, offering both durability and efficiency. The polished and powder-coated finish not only combats corrosion but also enhances the look under the hood.
