2006-2010 GM/CHEVROLET 6.6L DURAMAX 3" HIGH FLOW COLD SIDE INTERCOOLER PIPE WITH Y-BRIDGE KIT - RED
Unlock the true performance potential of your 2006–2010 GM 6.6L Duramax LBZ or LMM engine with this 3" High-Flow Cold Side Intercooler Pipe and Y-Bridge Kit. Designed to eliminate the restrictive factory piping and improve airflow, this kit is engineered for superior boost control, throttle response, and overall engine efficiency.
The cold-side pipe features mandrel-bent 3" aluminum tubing for smooth, unrestricted airflow from the intercooler to the intake manifold. Paired with a precision-engineered Y-Bridge, this kit replaces the factory plastic or cast components with high-strength TIG-welded aluminum—preventing boost leaks, cracking, and turbulence in high-performance applications.
Whether you're towing, racing, or daily driving, this upgrade provides a reliable and noticeable boost in performance while offering a clean engine bay appearance.

*If you have a 2006 or a 2010 model unit - MAKE SURE of your application to alleviate any issues with fitment as these are the break years and BDD IS NOT responsible for fitment issues and freight to return a mis-applicated part. Check your VIN or door jamb for a born on date to insure you have an LBZ/LMM truck. So make 100% sure on fitment prior to ordering this part as this is a factory drop ship program and restock fees will apply.
