Upgrade Your LB7 Duramax with HSP Diesel's 105-HSP-SB Intercooler Tubing

If you're driving a 2001-2004 Chevrolet Silverado 2500/3500 or GMC Sierra 1500/2500/3500 with the LB7 Duramax engine, you know that the factory charge air system can be a bottleneck for performance. The stock tubing is small-diameter and restricts airflow, leading to potential power loss. HSP Diesel recognized this issue and developed the 105-HSP-SB intercooler tubing kit to unleash the true potential of your rig.

Performance Gains You Can Feel

By increasing the tubing diameter to a robust 3 inches, this upgrade significantly enhances airflow compared to the factory setup. During dyno testing, we witnessed impressive horsepower and torque gains—proof that this often-overlooked component can make a substantial difference in your truck's performance. Keep in mind that actual power increases may vary based on your specific tuning, turbo setup, and any aftermarket fuel systems you have installed. However, one thing is clear: your intercooler system's airflow capacity directly affects your truck's power potential. Maximize it with HSP's upgraded charge tubes.
