2006-2007 Duramax Stage 3 High Flow Bundle Kit, Illusion Blueberry (WCF100503-IBB)

Wehrli's Stage 3 airflow package for the 2006-2007 LBZ Duramax: the full Stage 2 bundle plus a 3" stainless turbo down pipe. Intake, intake horn, Y-bridge, both intercooler pipes and the down pipe are all replaced, so the turbo breathes better in and out, and it all bolts on with no tuning.

The 3" two-piece Y-bridge with upper crossover and lower intercooler pipes flows 36% better than stock. The kit adds a 3" hot side and 3.5" cold side intercooler pipe with CNC-machined double O-ring flanges, a 4" aluminum intake pipe with air box, dry filter and Outerwears pre-filter cover, a 4.8" intake horn with PCV port, and the 3" stainless down pipe with heat wrap. Silicone boots, stainless T-bolt clamps, O-rings, intercooler outlet clip and hardware included. Retains factory connection points and sensors. Powder coated in your choice of colour.
