The HSP Diesel Cold Side Tube, part number 205-HSP-CUST, is designed to enhance the air charge system of the 2004.5-2005 Chevrolet and GMC LLY Duramax engines. This upgrade addresses the restrictive nature of the factory charge air system, which can hinder performance. By increasing the diameter to a robust 3 inches, this cold side tube significantly improves airflow, resulting in enhanced horsepower and torque.
During dyno testing, the HSP Cold Side Tube demonstrated a flow rate increase of 53% over the stock unit. This substantial improvement allows for better air delivery to the engine, which is crucial for maximizing power output. However, actual gains may vary based on vehicle tuning, turbo configurations, and aftermarket fuel systems. It’s important to note that the overall performance will depend on the intercooler system's ability to handle increased airflow.
This kit includes a 3-inch boot that connects seamlessly with your existing LLY factory replacement bridge. Installation is straightforward, but basic mechanical skills are recommended to ensure a secure fit.
This cold side tube is specifically compatible with:
Ensure your vehicle is within the specified range to take full advantage of the performance benefits offered by the HSP Diesel Cold Side Tube. This upgrade is a critical step in optimizing the air intake system for the LLY Duramax, making it a valuable addition for any serious performance build.
