2004.5-2005 Duramax LLY HSP Max Flow Bridge to HSP Cold Side (206-1-HSP)

The 206-1-HSP, also known as the Max Flow Bridge to HSP Cold Side for the 2004.5-2005 LLY Duramax-equipped Chevrolet and GMC trucks, is a performance-enhancing upgrade that integrates seamlessly with HSPs Cold Side Tube system.

Why Choose the Max Flow Bridge to HSP Cold Side?
The factory bridge and cold side piping on LLY trucks are restrictive and prone to boost leaks. Many owners prefer to upgrade these components as needed rather than replace factory parts that are known failure points. This Max Flow Bridge eliminates those issues by delivering improved airflow and durability.

What Makes This Bridge Kit Different?
This Max Flow Bridge is engineered to work exclusively with the HSP Cold Side Tube. Because HSPs Cold Side design alters both routing and diameter, the bridge is crafted to accommodate those changes while maximizing efficiency. It features a two-piece 3" diameter design to eliminate boost leaks and improve fitment. Each unit is precision cast and CNC machined for maximum performance and flawless installation.
