High Flow Bundle Kit Stage 1 for 2003-2007 5.9L Cummins Illusion Purple

This kit by Wehrli Custom Fabrication is designed for 2003-2007 5.9L Cummins engines, offering a 60% improvement in airflow. It includes a 3" hot/passenger side intercooler pipe and a 3.5" high-flow intake horn with a matching 3.5" cold/driver side intercooler pipe. Made from high-quality aluminum, it comes with an intake gasket, installation hardware, silicone boots, and stainless T-bolt clamps. The intake horn features two 1/8" NPT ports for boost pressure or water-methanol injection, and mounting points for the factory oil dipstick and wire harness. It's a direct bolt-on kit that requires no tuning and fits stock trucks. For 2003-2004 models, the larger 3.5" intake horn requires trimming of the plastic shroud over the throttle assembly for proper fitment.
