Unleash Maximum Airflow For Your Competition Cummins Build

When you are chasing serious horsepower out of your 2003-2018 RAM 2500 or 3500 Cummins, the factory intake manifold quickly becomes a restriction. The Wehrli Billet Individual Runner Intake Manifold is built for the kind of high RPM drag racing and pulling engines that demand every possible advantage. At the center of the design is a massive custom fabricated aluminum plenum that feeds precision CNC machined tapered runners. This layout helps move a significantly higher volume of air while distributing it more evenly to each cylinder. The result is improved volumetric efficiency and stronger power where competition engines live in the RPM range. If you have already invested in extensive cylinder head work, this manifold allows you to fully capitalize on those modifications. It is the kind of component you choose when you are no longer thinking about mild upgrades and are focused on extracting everything your 5.9L or 6.7L Cummins can deliver.

Precision Billet Runner Design Engineered For Extreme Applications

This intake manifold is not a simple bolt on part but a purpose built solution for extreme performance builds. The billet individual runner design features tapered runners that are CNC machined for consistent airflow characteristics across all cylinders. By balancing air distribution, the manifold supports more stable combustion under high boost and high RPM conditions. Installation requires custom fuel injection lines, custom intercooler piping, and cylinder head modifications including milling the cast intake shelf and drilling and tapping mounting holes. These requirements make it clear that this product is intended for advanced builds rather than stock daily drivers. For dedicated drag racing or pulling trucks that have already undergone significant engine work, this manifold becomes a key component in optimizing airflow efficiency. When your goal is maximum high RPM power output from a 2003-2018 5.9L or 6.7L Cummins platform, this billet intake provides the airflow foundation to support it.
