• Eliminates factory weak points prone to crushing and failure under high boost conditions
• Direct replacement for multiple MOPAR part numbers: 52014734AC, 52014734AA, 52014734AB, 52014735AB, 52014735AA
• Finished in striking Illusion Purple for a unique, performance-oriented appearance
• Made in the USA with precision craftsmanship and quality control

Construction & Design

The intake pipes are fabricated from heavy-duty 14 gauge aluminum tubing, chosen for its strength, heat resistance, and lightweight properties. The tubes feature mandrel bends that maintain a consistent diameter throughout curves, reducing airflow restrictions and turbulence. This design ensures smooth, efficient air delivery to the turbocharger, enhancing engine response and reliability.

Upgraded silicone boots replace the factory rubber components, offering superior durability against heat and pressure. These boots maintain a secure seal under extreme conditions, preventing boost leaks that can compromise performance and engine health.

Performance & Sound

By improving airflow efficiency and eliminating factory bottlenecks, the Wehrli High Flow Intake Bundle Kit contributes to quicker turbo spool-up and enhanced throttle response. While primarily focused on airflow improvements, users may also notice a subtle increase in intake sound, adding to the driving experience without excessive noise.

Installation & Fitment

This kit is designed as a direct bolt-on replacement for the factory intake pipes on 2013–2018 Ram 2500 and 3500 trucks with the 6.7L Cummins diesel engine. Installation requires no permanent modifications and can be completed with basic hand tools. The kit fits precisely to factory mounting points and connections, ensuring a straightforward upgrade process.

What's Included
