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 package addresses known weak points when pushing engine performance beyond stock power levels, replacing restrictive factory components with precision-engineered high-flow alternatives.

Kit Includes:

• 4-inch air intake kit with dry air filter and Outerwears pre-filter cover (WCF100346)
• 3-inch hot side (passenger) intercooler pipe (WCF100544)
• 3.5-inch cold side (driver) intercooler pipe with 3.5-inch upper intake manifold horn (WCF100528)

Performance Benefits:

• 60% improved airflow over stock components for increased turbo spool-up and throttle response
• Decreased exhaust gas temperatures (EGTs) for safer, more efficient operation
• Eliminates horsepower-robbing boost leaks caused by aging factory components
• Enhanced engine efficiency and power delivery across the RPM range

Fabricated from precision mandrel-bent 14-gauge steel piping and CNC-machined billet aluminum components, every piece is manufactured in the USA to Wehrli's exacting standards. Available in multiple powder-coated color options including WCFab Red, Gloss Black, and Gloss White with standard brushed tags for a custom appearance that matches your build.
