GM Duramax LML - Intercooler Pipe & Boot Kit (2011-2016)
Type: Intercooler Pipe
Smoother flow. Cooler temps. More power for your LML Duramax.
Eliminate airflow restrictions and unlock real performance gains with this Intercooler Pipe & Boot Kit for the 2011–2016 LML Duramax. Factory piping is narrow and full of sharp bends that choke airflow and raise EGTs—especially under load. This upgraded kit delivers smoother, cooler airflow with polished 3” aluminum piping and heavy-duty silicone boots built for durability under extreme heat and boost.
