If you plan on getting the most out of your Duramax, you need the air for it! Remove restrictive stock piping with Wehrli Custom Fabrication's 4" Cold Air Intake Kit with a variety of colors to show off your truck every time you pop the hood.

NOTE: While some colors are kept in stock, other colors will take an extra 10-15 business day delay in powder coating.

If you’re looking to improve performance and efficiency on your LML Duramax, upgrading your intake system is one of the most effective first steps. The Wehrli Custom Fab LML Duramax Cold Air Intake Kit with Air Box is designed to increase airflow, improve throttle response, and give your engine bay a clean, custom appearance.

This intake replaces the restrictive factory air box with a high-flow intake tube and sealed air box system, helping deliver cooler, denser air to your turbocharger. Improved airflow allows your truck to respond quicker, perform better under load, and maintain consistent power whether you're towing, daily driving, or running performance tuning.

The sealed air box design helps reduce heat soak from the engine bay, ensuring your intake pulls in cooler outside air for improved combustion efficiency. This is especially important for LML trucks that see heavy towing or extended drive times.

Constructed from high-quality fabricated materials, this intake kit is built for durability and long-term reliability. Each unit is finished in your choice of WCFab custom powder coat colors, giving your engine bay a standout look every time you open the hood.

Work great
Just to let people know, they dont work very well unless there is something in the air to reflect the light off like sand, rain or fog. I like them for trail riding in the dunes. More noticable than just a normal lighted whip.
