HSPThe Problem with the Factory Cold Side Pipe
The OEM cold side intercooler pipe on the 2020–2024 L5P Duramax is functional, but far from optimal. Constructed from rubber, the stock tube is vulnerable to heat, pressure, and age-related degradation. This often leads to splits or leaks, reducing performance and risking turbocharger damage.
The HSP Solution
HSP Diesel has engineered a premium alternative designed for both long-term durability and high-performance functionality.
Key Features
3.5" Mandrel-Bent Aluminized Steel Pipe:
Offers smooth, unrestricted airflow for better throttle response, improved reliability, and a cleaner engine sound.
Billet Coupler Set:
Includes a CNC-machined billet aluminum
intercooler
coupler and a billet throttle body coupler for the strongest, most secure connections available—eliminating weak points common in OEM designs.
Reinforced Silicone Boots & Stainless Steel T-Bolt Clamps:
Leak-free performance under high boost thanks to high-strength boots and T-bolt clamps.
Custom Powder Coat Options:
Multiple finishes are available to suit your truck’s aesthetic and complete the under-hood look.
