You can increase your fuel systems but if your air intake doesn't match the added fuel you're burning then you are simply wasting fuel. Increase your Duramax air with Wehrli Custom Fab 4" Cold Air Intake Kit! If you’re looking to wake up your LLY Duramax, airflow is one of the first places to start. The LLY Duramax Cold Air Intake Kit with Air Box is designed to improve airflow, throttle response, and overall engine efficiency while giving your engine bay a clean, custom look.
NOTE: While some colors are kept in stock, other colors will take an extra 10-15 business day delay in powder coating.
This intake system replaces the restrictive factory air box with a high-flow intake design and sealed air box, helping deliver cooler, denser air to your turbo. The result is improved performance, better throttle response, and more efficient operation especially under load or towing conditions.
Built with high-quality fabricated components, this kit is designed for durability and long-term reliability. The included air box helps protect the filter from engine bay heat, ensuring consistent performance whether you're daily driving or pushing your truck harder.
Finished in your choice of WCFab custom powder coat colors, this intake doesn’t just perform; it stands out every time you pop the hood.
