Wehrli High Flow Bundle Intake Kit Stage 3 01-04 D-Max LB7 Gloss Black Gloss Black 100712-GB

The WCFab 2001-2004 GM LB7 6.6L Duramax Stage 3 High Flow Intake Bundle Kit combines the Stage 1 High Flow Bundle, Stage 2 Intake Kit, and 3" Down Pipe into a single package. This kit provides increased airflow for the turbo and engine, leading to improved efficiency, throttle response, and turbo spool up. It replaces the restrictive OEM LB7 Y-Bridge, passenger side intercooler pipe, and driver side intercooler pipe with a high-flow, 3” mandrel bent aluminum piping kit and a TIG welded, CNC machined billet y-bridge base. The kit also includes a high flow, fabricated aluminum air intake pipe and air box enclosure with a dry filter assembly, a hydrophobic pre-filter cover, and a 4" intake horn. Upgraded high-quality silicone boots and stainless steel T-bolt clamps are included to increase reliability and eliminate boost leaks. It also includes a Fuel Pressure Regulator Valve (FPRV) Block Off Kit and a 3" High Flow Down Pipe. The entire assembly is finished in a custom powder coat color.
