2007.5-2010 Duramax Stage 2 High Flow Bundle Kit, Illusion Blueberry (WCF100438-IBB)

Wehrli's Stage 2 airflow package for the 2007.5-2010 LMM Duramax: the Stage 1 bundle plus the Stage 2 intake in one kit. It replaces the slip-fit factory Y-bridge, both intercooler pipes, the plastic intake and the intake horn, so every restriction and leak point between the air filter and the heads is gone, and it 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, and a 4.8" intake horn with PCV port. 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.
