Wehrli Custom Fab 4" Cold Air Intake Kit With Air Box 07.5-10 GM 6.6L Duramax LMM

Holding its breath is not something we want our Duramax to do. Your GM truck requires diesel fuel and cold compressed air to get you where you want to go with the things you want to bring with you. Make sure your engine has all the air it needs with a cool look that will put a smile on your face every time you pop the hood with Wehrli Custom Fabrication's 4" Cold Air Intake Kit. 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 LMM Duramax, airflow is one of the most effective upgrades you can make. The LMM Duramax Cold Air Intake Kit with Air Box is engineered to increase airflow, improve throttle response, and give your engine bay a clean, custom appearance. This intake system replaces the restrictive factory air box with a high-flow intake tube and sealed air box design, helping deliver cooler, denser air to your turbocharger. By improving airflow efficiency, your truck responds quicker, performs better under load, and maintains more consistent power whether you're towing, daily driving, or running performance tuning. The sealed air box helps minimize heat soak from the engine bay, ensuring your intake system pulls in cooler outside air for improved combustion efficiency. This is especially important for maintaining performance during heavy towing or extended driving conditions. Built from high-quality fabricated materials, this intake is designed for long-term durability and reliability. Each kit is finished in your choice of WCFab custom powder coat colors, giving your LMM a standout look every time you open the hood.
