GM Duramax LML - Intercooler Pipe & Boot Kit (2011-2016)
Eliminate airflow restrictions and unlock real performance gains with this Intercooler Pipe & Boot Kit for your 2011-2016 LML Duramax. The factory piping is full of sharp bends and narrow passages that choke airflow and raise EGTs—especially under load or boost. This upgraded kit features polished 3” aluminum piping and heavy-duty silicone boots that deliver smoother, cooler airflow and long-term durability, even under extreme conditions.
Key Features:
- Polished 3' Aluminum Piping: Smoother bends and larger diameter piping improve boost response and reduce restriction.
- Silicone Boots: Multi-layered, oil-resistant, and built to handle high heat and high boost without failing.
- Improved Performance: Increases airflow, reduces EGTs, and supports tuned or stock setups.
- Complete Hardware Kit: Includes everything needed for a clean, secure installation—no extra parts required.
