Wehrli Intake Kit

2010–2012 Dodge Ram 2500/3500 6.7L Diesel

Part #: WCF100875-GM

Overview

The Wehrli 4-inch Intake Kit in Gun Metal is a high-performance upgrade designed specifically for 2010 to 2012 Dodge Ram 2500 and 3500 models equipped with the 6.7L Cummins diesel engine. This intake system replaces the factory’s restrictive plastic intake components with a fully fabricated aluminum intake pipe and air box assembly, engineered to optimize airflow and enhance engine efficiency. Ideal for diesel enthusiasts seeking improved horsepower, torque, and throttle response, this kit draws in cooler air from the inner fender area, contributing to lower intake temperatures and better overall engine performance.

Built to complement the OEM or VGT turbocharger setups, the Wehrli intake kit delivers a noticeable improvement in engine breathing without compromising reliability or fitment. Its robust construction and thoughtful design make it a practical upgrade for daily drivers and performance-focused builds alike.

Key Features

This intake kit offers a range of advanced features that enhance both performance and durability:

• High-flow 4-inch diameter intake piping for increased air volume and velocity
• Fabricated aluminum construction with smooth aerodynamic bends to reduce turbulence
• Integrated air box enclosure designed to draw cold air from the inner fender area
• Dry filter assembly with hydrophobic pre-filter cover to protect the MAF sensor and turbo
• Removable air box lid for easy filter inspection and maintenance
• Includes high-quality silicone boot, seals, and stainless steel T-bolt clamps for secure, leak-free connections
• Finished in durable Gun Metal powder coat for corrosion resistance and a custom look
• Designed specifically for 2010–2012 Dodge Ram 2500/3500 6.7L Cummins diesel engines
• Made in the USA with precision craftsmanship and quality control

Construction & Design

The Wehrli intake kit is crafted entirely from lightweight, corrosion-resistant aluminum, ensuring long-lasting durability under demanding conditions. The 4-inch piping features smooth, aerodynamic bends that optimize airflow dynamics, reducing intake air turbulence and pressure drop. This design enhances air velocity and volume delivered to the turbocharger, supporting improved combustion efficiency.

The air box enclosure is engineered to isolate the intake filter from engine heat while drawing cooler ambient air from the inner fender area. This strategic placement helps reduce intake air temperatures, which can improve power output and engine longevity. The kit’s components are finished with a premium Gun Metal powder coat that resists chipping and corrosion, maintaining a clean, custom appearance.

Performance & Sound

By replacing the restrictive factory plastic intake parts with large-diameter aluminum piping and a well-sealed air box, this intake kit significantly improves airflow to the turbocharger. The result is enhanced horsepower and torque, quicker throttle response, and reduced turbo lag. Additionally, the smooth bends and larger diameter piping contribute to a more aggressive engine and turbo sound during acceleration, providing an engaging driving experience without excessive noise.

Installation & Fitment

The Wehrli 4-inch Intake Kit is designed for a direct bolt-on installation on 2010–2012 Dodge Ram 2500 and 3500 trucks equipped with the 6.7L Cummins diesel engine and OEM or VGT turbochargers. The kit includes all necessary hardware, silicone boots, and clamps to ensure a secure and leak-free fit. Installation requires no permanent modifications, making it a straightforward upgrade for experienced DIYers or professional installers.

Please note that the air box included in this kit is not compatible with the intake pipe from kit WCF100863.
