Wehrli Intercooler Pipes Kit

2013–2018 Ram 2500 / 3500 6.7L Diesel

Part #: WCF100423-DG

Overview

The Wehrli 3.5-inch Intercooler Pipes Kit is a Stage 1 High Flow Bundle designed specifically for the 2013–2018 Ram 2500 and 3500 equipped with the 6.7L Cummins diesel engine. This kit enhances the airflow between the turbocharger and engine, resulting in improved throttle response, turbo spool-up, and overall engine efficiency. It addresses common weaknesses found in the factory intercooler piping that can cause boost leaks or failures under demanding driving conditions and high-performance use.

Ideal for diesel enthusiasts and professionals seeking reliable upgrades, this kit replaces the restrictive factory pipes with larger diameter, heavy-duty components engineered for durability and optimized airflow.

Key Features

Engineered to deliver superior performance and reliability, the Wehrli Intercooler Pipes Kit offers the following key features:

• Upgraded 3.5-inch diameter pipes for increased airflow and reduced boost lag
• Heavy-duty 14 gauge aluminum tubing with smooth mandrel bends for optimized flow and strength
• High-quality silicone boots designed to withstand higher pressure and temperatures than factory boots
• Eliminates common boost leak points found in OEM pipes
• Direct replacement for factory intercooler pipes with no modifications required
• Improves turbo spool-up and throttle response for enhanced driving experience
• Made in the USA with premium materials and craftsmanship
• Replaces MOPAR part numbers 52014734AC, 52014734AA, 52014734AB, 52014735AB, and 52014735AA

Construction & Design

The intercooler pipes are constructed from heavy-duty 14 gauge aluminum tubing, chosen for its strength, durability, and resistance to corrosion. The pipes feature smooth, aerodynamic mandrel bends that maintain consistent diameter throughout the bends, minimizing airflow restrictions and turbulence. This design ensures maximum efficiency and longevity under high boost pressures.

The kit includes upgraded silicone boots that exceed factory specifications for pressure and temperature tolerance, reducing the risk of boot failure and boost leaks. Every component is precision-engineered and manufactured in the USA to meet rigorous quality standards.

Performance & Sound

By replacing the factory’s small diameter and often crushed intercooler pipes, this kit significantly improves airflow between the turbocharger and engine. The result is quicker turbo spool-up, enhanced throttle response, and improved overall engine efficiency. While primarily focused on performance gains, the improved airflow can also contribute to a smoother, more responsive driving experience.

Installation & Fitment

The Wehrli Intercooler Pipes Kit is designed as a direct bolt-on replacement for the factory intercooler pipes on 2013–2018 Ram 2500 and 3500 trucks equipped with the 6.7L Cummins diesel engine. Installation requires no cutting, welding, or modifications, making it a straightforward upgrade for professional installers or experienced enthusiasts. The kit includes all necessary silicone boots and clamps for a secure fit.

What's Included

• 3.5-inch diameter heavy-duty aluminum intercooler pipes
• High-quality silicone boots rated for increased pressure and temperature
• All required clamps and hardware for installation

Ideal For

This intercooler pipes kit is ideal for Ram 2500 and 3500 owners looking to improve their 6.7L Cummins diesel’s turbo efficiency and reliability. It suits daily drivers, work trucks, and performance enthusiasts who demand better throttle response, reduced turbo lag, and a more robust intercooler system capable of handling increased boost pressures without failure.
