HSP Diesel 2006-2007 LBZ Duramax Cold Air Intake - 302-HSP

HSP Cold Air Intake for 2006-2007 Chevrolet / GMC Duramax LBZ

Part Number: 302-HSP

The 302-HSP is best known as the HSP Cold Air Intake for the 2006-2007 LBZ Duramax-equipped Chevrolet and GMC trucks. This cold air intake system is one of the best performance upgrades available for your truck.

Why Choose the HSP Cold Air Intake for the LBZ Duramax?

The factory intake on the LBZ Duramax has a restrictive design that limits performance and airflow. Stock filter elements wear out quickly, resulting in reduced reliability and efficiency. Replacing the intake with a high-performance system like the HSP Cold Air Intake unlocks hidden power and improves dependability.

What Sets the HSP Cold Air Intake Apart?

Dyno-tested gains average an increase of 20 horsepower and 58 lb-ft of torque. The HSP Cold Air Intake features a 4.5" mandrel-bent tube, creating a smooth, consistent, and free-flowing path for air. This dramatically improves airflow over stock designs. The custom-designed heatshield box also blocks hot engine bay air from entering the intake, drawing in cooler, denser air for better combustion and performance.
