GM Duramax LML Intercooler Pipe & Boot Kit (2011–2016)

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 high boost. This upgraded kit features polished 3” aluminum piping and heavy-duty silicone boots, delivering smoother, cooler airflow and long-term durability even under extreme conditions.

Key Features:

• Polished 3" Aluminum Piping: Larger diameter and smoother bends improve boost response and reduce restriction.

• Heavy-Duty Silicone Boots: Multi-layered, oil-resistant, and built to withstand high heat and high boost without cracking or collapsing.

• Performance Gains: Improves airflow, reduces EGTs, and supports both tuned and stock setups.

• Complete Hardware Kit: All clamps and fittings included for a secure, leak-free installation.

Smoother Flow. Cooler Temps. More Power.

This kit fixes one of the most overlooked bottlenecks in your Duramax’s performance—the restrictive stock intercooler pipes. Whether you’re towing heavy, daily driving, or running performance tunes, you’ll see cooler intake temps, lower EGTs, and improved throttle response. The polished aluminum finish also adds a sleek, high-performance look under the hood.
