Product Description

The Volant 155666 PowerCore Cold Air Intake System is engineered for heavy-duty GM trucks equipped with the 6.6 L Duramax LML V8 engine from 2013-2016. The system replaces the restrictive factory intake with a larger closed-box design and a high-velocity venturi adapter, allowing cooler and denser air to enter the engine for improved efficiency and performance. Its PowerCore® dry filter offers long maintenance-free life - up to approximately 100,000 miles - while maintaining excellent filtration and airflow.

Constructed from heat-resistant molded polyethylene with premium couplers and clamps, this intake installs in about an hour using the vehicle's original mounting points. The improved airflow often translates to better throttle response and potential horsepower gains over stock systems. This part is not CARB exempt and does not carry a California Executive Order, so verify local emissions requirements before purchase.
