Wehrli Custom Fabrication WCF100680-GB Stage High Flow Intake Bundle Kit - 2 Gloss Black

The Wehrli Custom Fabrication Stage 2 High Flow Intake Bundle Kit delivers a complete airflow upgrade for 2003-2007 Dodge Ram 2500/3500 trucks equipped with the 5.9L Cummins diesel engine. This comprehensive performance package combines precision-engineered intake components with high-flow intercooler piping to eliminate restrictive factory parts and unlock improved throttle response, faster turbo spool-up, and lower exhaust gas temperatures.

Fabricated in the USA from precision mandrel-bent 14-gauge aluminum piping and CNC-machined billet components, this bundle includes everything needed for a complete intake system overhaul. The kit features a 4-inch intake system with dry air filter and Outerwears pre-filter cover, a 3-inch hot side (passenger) intercooler pipe, a 3.5-inch cold side (driver) intercooler pipe, and a 3.5-inch high-flow intake horn that flows 60% better than stock components.

Key Features:

• Complete Stage 2 intake upgrade bundle with all necessary components
• 3.5-inch high-flow intake horn with smooth radius bends for optimized airflow
• 4-inch intake system with dry air filter and protective Outerwears pre-filter cover
• 3-inch hot side intercooler pipe and 3.5-inch cold side intercooler pipe
• Two 1/8-inch NPT accessory ports on upper intake manifold for boost gauges or water-methanol injection
• Durable gloss black powder coat finish for long-lasting appearance and corrosion resistance
• Heavy-duty silicone boots and stainless steel T-bolt clamps for secure, leak-free connections
• Mounting hardware and gaskets included for complete installation
• Retains oil dipstick location and OEM wire harness routing
• Compatible with stock and performance drop-in Holset turbochargers and OEM intercoolers
• No tuning required - direct bolt-on installation
• Made in the USA

This kit eliminates horsepower-robbing boost leaks caused by aging, failure-prone OEM components while providing a proven 60% improvement in airflow over stock parts. The result is quicker turbo spool-up, improved throttle response, and decreased EGTs - ideal for towing, daily driving, or performance-tuned applications. The bundle saves money compared to purchasing components individually.

Installation Note: 2003-2004 models may require slight trimming of the plastic throttle assembly shroud to accommodate the larger 3.5-inch intake horn.
