2003-2007 5.9L CUMMINS HIGH FLOW INTAKE BUNDLE KIT Semi-Gloss Black

This kit upgrades the air intake plumbing with precision mandrel bent 14 gauge piping and CNC machined billet components. It includes a 4-inch Air Intake Kit (WCF100346), a 3-inch hot side intercooler pipe (WCF100544), and a 3.5-inch cold side intercooler pipe with a 3.5-inch upper intake manifold/horn (WCF100528). It's designed to improve airflow and efficiency, eliminate boost leaks, and is compatible with stock and performance upgrade drop-in style Holset turbochargers and OEM-style intercoolers. The cold side upgrade is proven to improve airflow over stock components by 60%, leading to improved turbo spool up, increased throttle response, and decreased EGTs. The upper intake manifold has two 1/8" NPT accessory ports for boost pressure readings or water methanol injection.
