Upgrade Your LB7 Duramax Charge Air System
The LB7 Duramax comes with a factory charge air system that’s a bit on the restrictive side. We noticed that those small-diameter factory tubes were holding back potential power, so we took action! By increasing the tubing size to a robust 3 inches, we unlocked significant power gains over the stock intercooler system. During our dyno testing of the HSP upgraded intercooler tubing, we were amazed by the horsepower and torque improvements from what many might overlook. Keep in mind that power increases can vary between models due to factors like tuning calibrations, turbo options, and aftermarket fuel systems. One thing is clear: your intercooler system's airflow is key to your truck's performance. Using the HSP upgraded charge tubes is a smart way to maximize your truck's potential.
