Plastic doesn't deserve a place in a high performance Cummins. Replace that failure prone OEM intercooler pipe and unlock improved airflow and performance with the Wehrli Custom Fab 3.5" High Flow Intake Horn & Intercooler Pipe Kit for 1998.5–2002 Dodge Ram trucks equipped with the 5.9L Cummins. Engineered to eliminate restrictive factory components, this complete system increases airflow velocity, improves turbo efficiency, and helps support higher horsepower builds.

NOTE: While some colors are kept in stock, other colors will take an extra 10-15 business day delay in powder coating.

This kit replaces undersized and failure-prone OEM intake and intercooler piping with high-quality mandrel-bent aluminum components designed to handle increased boost pressure and demanding diesel applications.

Increase Airflow & Turbo Efficiency

The factory intake horn and intercooler piping on early 24-valve Cummins engines are known for restricting airflow and limiting performance potential. This high-flow system increases intake volume and reduces turbulence, allowing your turbocharger to operate more efficiently and deliver improved throttle response.

Whether you're running a stock turbo or upgraded setup, this kit helps reduce boost pressure loss and supports consistent airflow under load.

Built for Performance & Durability

Constructed from heavy-duty aluminum, this kit is designed to withstand higher boost pressures and eliminate common failure points found in factory plastic piping. Reinforced silicone boots and stainless T-bolt clamps ensure a secure seal, reducing the risk of boost leaks in high-performance applications.

Perfect for towing, daily driving, or performance builds, this upgrade provides long-term reliability and improved drivability.
