Wehrli Custom Fabrication WCF100680-IP Stage 2 Intake Bundle Kit Illusion Purple

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 engine. This comprehensive performance package replaces restrictive factory intake components with precision-engineered mandrel-bent aluminum piping and CNC-machined billet components, all finished in eye-catching Illusion Purple two-stage powder coating.

What's Included:

• 4-inch air intake system with premium dry media air filter
• Outerwears pre-filter cover for added protection in dusty conditions
• 3-inch hot side (passenger) intercooler pipe
• 3.5-inch cold side (driver) intercooler pipe with intake horn
• Heavy-duty silicone boots and stainless steel T-bolt clamps

Performance Benefits:

• Flows 60% better than stock cold side components for dramatically improved airflow
• Improves turbo spool-up and throttle response
• Reduces exhaust gas temperatures (EGTs) for safer towing and performance
• Eliminates boost leaks from aging OEM components
• Maintains consistent boost pressure under load

Constructed from 14-gauge mandrel-bent aluminum piping with durable powder coat finish, this kit is engineered for maximum airflow and long-term reliability. All components are precision-fabricated in the USA to ensure proper fitment and performance. The larger 3.5-inch intake horn features smooth, optimized bends for improved air delivery to the turbocharger. Installation is straightforward with all necessary hardware included, though 2003-2004 models may require slight trimming of the throttle assembly shroud to accommodate the larger intake horn. No tuning required—this is a true bolt-on performance upgrade.
