Wehrli Intercooler Pipes Kit

2013–2018 Ram 2500 / 3500 6.7L Diesel

Part #: WCF100423-BS

Overview

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

Ideal for diesel enthusiasts and professionals seeking reliable performance improvements, this kit replaces the restrictive factory pipes with a robust, high-flow solution engineered to withstand the rigors of heavy-duty use.

Key Features

Engineered to optimize airflow and durability, the Wehrli intercooler pipes kit offers the following benefits:

• Upgraded 3.5-inch diameter pipes for significantly improved airflow compared to factory components
• Heavy-duty construction eliminates common boost leak points and weak factory pipe failures
• Includes premium silicone boots rated for higher pressure and temperature to prevent blown factory boots
• Mandrel-bent aluminum tubing ensures smooth, aerodynamic bends for optimized flow and reduced turbulence
• Direct replacement for multiple MOPAR part numbers, ensuring perfect fitment and compatibility
• Designed to enhance turbo spool-up and throttle response for a more responsive driving experience
• Made in the USA with high-strength 14 gauge aluminum for long-lasting durability

Construction & Design

The intercooler pipes are crafted from heavy-duty 14 gauge aluminum tubing, providing superior strength and resistance to cracking or deformation under high boost pressures. The smooth mandrel bends maintain consistent internal diameter throughout the piping, minimizing airflow restrictions and turbulence. The Bengal Silver finish not only offers a clean, professional look but also provides corrosion resistance for extended service life.

Upgraded silicone boots included in the kit are engineered to withstand higher temperatures and pressures than the factory boots, significantly reducing the risk of failure during demanding operation. This combination of materials and design ensures a reliable, high-performance upgrade that stands up to the rigors of diesel truck use.

Installation & Fitment

This intercooler pipes kit is a direct bolt-on replacement for 2013–2018 Ram 2500 and 3500 trucks equipped with the 6.7L Cummins diesel engine. Installation requires no modifications and utilizes existing mounting points and hardware for a straightforward upgrade. The kit is designed to fit precisely, ensuring a secure and leak-free connection between the turbocharger and engine intercooler system.

What's Included

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

Ideal For

This intercooler pipes kit is perfect for Ram 2500 and 3500 owners looking to improve their truck’s turbo efficiency and reliability. It is especially suited for those who tow heavy loads, run aftermarket performance upgrades, or operate their trucks in demanding conditions where factory intercooler piping may be prone to failure. Whether for daily driving, work, or performance applications, this kit provides a durable and effective solution to boost-related issues.
