High Flow Bundle Kit Stage 2 for 2006-2007 Duramax LBZ Bronze Chrome

The Wehrli Custom Fabrication Stage 2 High Flow Intake Bundle Kit is an upgrade for 2006-2007 LBZ Duramax engines, combining the Stage 1 High Flow Bundle and Stage 2 intake Kit. It increases airflow for improved efficiency, throttle response, and turbo spool up by replacing restrictive factory plastic parts with high-flow components. This kit includes a 4-inch aluminum intake pipe with air box enclosure, dry filter assembly, Outerwears pre-filter cover, a 4.8-inch intake horn with PCV port, a 3-inch hot side intercooler pipe, and a 3.5-inch cold side intercooler pipe. It also features WCFab's signature 3-inch Two-Piece Y-Bridge with upper crossover and lower intercooler pipes, flowing 36% better than stock. CNC machined flanges with double O-ring seals prevent boost leaks, and high-quality silicone boots, stainless steel T-bolt clamps, O-rings, intercooler outlet clip, and all necessary installation hardware are included. The kit retains factory connection points and sensors, requires no tuning, and is a bolt-on installation compatible with stock trucks. Made in the USA.
