HSP L5P Cold Side Intercooler Pipe HSP-D-605-2-HSP-Raw - Raw

Upgrade the intercooler pipe on your L5P Duramax with the HSP L5P Cold Side Intercooler Pipe HSP-D-605-2-HSP-Raw - Raw. Designed as a direct replacement for the factory setup, this kit eliminates common weak points in the OEM design while improving airflow, durability, and long-term peace of mind.

The Problem with the Factory Cold Side Pipe
The OEM cold side intercooler pipe on your L5P Duramax is functional, but far from optimal. Constructed from rubber, the stock tube is vulnerable to degradation over time due to heat, pressure, and general wear. This often results in splits or leaks that can significantly reduce performance and potentially lead to turbocharger issues.

The HSP Solution
HSP Diesel has engineered an alternative designed to deliver long-term reliability and improved performance.

3.5" Mandrel-Bent Aluminized Steel Pipe
Replaces the OEM rubber tubing with a rigid steel pipe, ensuring smooth and unrestricted airflow, increased durability, and a refined engine sound.

Billet Coupler
CNC-machined billet aluminum coupler creates a robust and reliable connection point, eliminating a common failure spot in the OEM setup.

High-Strength Silicone Boots & Stainless T-Bolt Clamps
Reinforced silicone boots paired with stainless T-bolt clamps provide a secure, leak-free seal even under high boost pressure.
