High Flow Bundle Kit Stage 1 2006-2007 Duramax LBZ Fluorescent Orange

This Stage 1 High Flow Bundle Kit is a performance upgrade for 2006-2007 GMC/Chevrolet 6.6L Duramax LBZ engines. It improves airflow and strengthens the induction system by replacing the factory's weak, slip-fit Y-bridge with a robust, bolt-together 3-inch high-flow Y-bridge for a secure seal under high boost. The kit includes 3-inch upper and lower intercooler pipes with mandrel bends and CNC-machined billet flanges, and a 3.5-inch high-flow passenger (cold) side intercooler pipe. These components replace smaller/weaker OEM parts and are designed to withstand increased boost pressures, eliminate leaks, and feature a custom powder coat finish.
