2004.5-2007 Duramax LLY/LBZ HSP Diesel Cold Air Intake Bundle (081-HSP)
The HSP Cold Air Intake Bundle is the perfect first step toward improving airflow and performance in your 2004.5-2007 Duramax-equipped Chevrolet and GMC truck. With upgraded components and a design that focuses on power and efficiency, this bundle helps your truck breathe easy and run strong.
What Is the HSP Cold Air Intake Bundle?
This bundle combines two major performance upgrades: a Cold Air Intake and a VGT Intake Mouthpiece. These components replace restrictive factory parts that limit airflow and hinder your engines potential. With improved construction and design, this kit gives you a noticeable bump in power and engine response.
Cold Air Intake
Built from hand-fabricated, high-grade metal and featuring a 4.5" mandrel-bent intake tube, HSPs Cold Air Intake reduces turbulence and increases airflow. The included heat shield box protects the system from underhood heat, ensuring cooler and denser air reaches the turbo. On the dyno, this intake has shown gains of up to 20 HP and 58 lb-ft of torque. Cooler intake air means more power and better overall engine performance.
VGT Intake Mouthpiece
Hand-fabricated for smooth transitions and precise fitment, the VGT Intake Mouthpiece optimizes airflow between the intake and turbo. It uses a high-strength O-ring seal at the turbo inlet to prevent leaks and ensure maximum efficiency. This piece is essential for unlocking the full potential of your Cold Air Intake and improving throttle response and turbo spool-up.
