Upgrade your Duramax’s performance and reliability with the SPELAB 3-Inch Y-Bridge and Cold Side Intercooler Pipe Kit. Designed for 2006–2010 6.6L LBZ and LMM Duramax engines, this kit replaces the restrictive factory plastic components with high-flow mandrel-bent aluminum pipes and reinforced silicone boots. The addition of a free-flowing Y-Bridge enhances throttle response, reduces boost drop, and ensures consistent airflow under heavy loads or performance tuning.
