Boost Performance with a High-Flow Intake System
The Wehrli WCF100346 4in Cold Air Intake Kit is engineered to improve horsepower, torque, and throttle response in your 2003–2007 Dodge Ram 5.9L Cummins. This intake replaces your restrictive factory system with a 4-inch mandrel-bent aluminum intake tube and a high-flow oiled air filter, allowing your turbocharger to breathe easier and perform more efficiently.
Enhanced Airflow for Maximum Gains
Designed to increase the volume of cool, dense air entering the turbo, this kit reduces turbo lag and supports higher boost levels, making it a perfect upgrade for both stock and modified trucks. The included air filter offers superior filtration while minimizing restriction, and the powder-coated tubing resists corrosion and adds a clean finish under the hood.
Dyno-Tested Performance Improvements
This Wehrli intake system provides noticeable power gains, especially when paired with additional performance upgrades such as tuning, exhaust, or turbo enhancements. Expect better throttle response, increased efficiency, and enhanced engine sound.
