Wehrli Stage 1 High Flow Intake Bundle Kit

2013–2018 Ram 2500 / 3500 6.7L Diesel

Part #: WCF100423-BC

Overview

The Wehrli Stage 1 High Flow Intake Bundle Kit is engineered specifically for 2013–2018 Ram 2500 and 3500 trucks equipped with the 6.7L Cummins diesel engine. Designed to replace the restrictive factory intake pipes, this kit significantly improves airflow between the turbocharger and the engine. By eliminating common weak points found in the stock setup, it enhances throttle response, turbo spool-up time, and overall engine efficiency. This upgrade is ideal for diesel enthusiasts seeking reliable performance gains and durability in demanding driving conditions.

Whether you use your Ram for heavy-duty work or high-performance applications, the Stage 1 kit addresses boost leaks and potential failures caused by the factory’s small diameter, crushed pipes and lower quality silicone boots. It delivers a robust, long-lasting solution that supports increased boost pressure and heat resistance.

Key Features

This high flow intake bundle kit offers a range of benefits designed to optimize your Ram’s turbo system:

• Replaces factory intake pipes with heavy duty 3.5" diameter aluminum tubes for improved airflow
• Includes upgraded silicone boots rated for higher pressure and temperature to prevent boot failures
• Mandrel-bent aluminum pipes ensure smooth, aerodynamic flow with no restrictions
• Eliminates boost leaks common in factory components under high load
• Constructed from durable 14 gauge aluminum for long-lasting strength and corrosion resistance
• Direct replacement for multiple MOPAR part numbers: 52014734AC, 52014734AA, 52014734AB, 52014735AB, 52014735AA
• Designed and manufactured in the USA with quality craftsmanship

Construction & Design

The Wehrli Stage 1 Intake Bundle Kit is built from heavy duty 14 gauge aluminum tubing, providing superior strength and durability compared to the factory’s thinner, crushed pipes. The aluminum is mandrel bent to maintain consistent internal diameter and smooth airflow, reducing turbulence and pressure drop. This precision engineering ensures optimal turbo efficiency and engine breathing.

High-quality silicone boots included in the kit are designed to withstand elevated boost pressures and higher operating temperatures, eliminating the common failure points seen with stock rubber boots. The bronze chrome finish not only adds corrosion resistance but also a distinctive, professional appearance under the hood.

Performance & Sound

By improving airflow and eliminating boost leaks, this intake kit enhances turbo spool-up and throttle response, resulting in a more responsive driving experience. While primarily focused on performance and reliability, the improved airflow can also contribute to a subtle increase in turbo sound, providing a more aggressive and satisfying engine note without excessive noise.

Installation & Fitment

The Wehrli Stage 1 High Flow Intake Bundle 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 engine. Installation requires no permanent modifications and can be completed with basic hand tools. The kit includes all necessary silicone boots and clamps to ensure a secure, leak-free fit.

Professional installation is recommended for optimal results, but experienced DIYers will find the process straightforward and well-supported by Wehrli’s detailed instructions.

What's Included
