Cold Air Intake System for LBZ Duramax

The HSP 302-HSP Cold Air Intake is engineered to be a direct performance upgrade for 2006-2007 Chevrolet and GMC trucks equipped with the LBZ Duramax engine (VIN Code 2 or D). It addresses the limitations of the factory intake system, which is known for its restrictive design, hindering optimal performance and airflow. By replacing stock components that degrade quickly, this system enhances reliability and efficiency. The HSP Cold Air Intake is designed to unlock significant hidden power, with dyno-tested average gains of 20 horsepower and 58 lb-ft of torque. It features a 4.5-inch mandrel-bent tube constructed from 304 stainless steel, ensuring a smooth and consistent path for air. This design dramatically improves airflow compared to stock configurations. Additionally, a custom-designed heat shield box effectively blocks hot engine bay air, drawing in cooler, denser air for improved combustion and overall performance. The system also includes CNC-machined sensor blocks for a precise fit and upgraded high-strength silicone boots. This kit includes a 4.5" cold air intake tube, a 4.5" heat shield box with lid, a 4.5" filter, and all necessary hardware for installation, including various T-bolt clamps, rivets, screws, and trim lock. The heat deflection box features an airtight seal to prevent hot air intake. HSP offers powder coating options for the intake tube and clamps to match your engine bay aesthetics. HSP Diesel backs this product with a No BS Limited Lifetime Warranty.
