    Lower critical exhaust gas temperatures (EGTs), eliminate frustrating boost leaks, and maximize your engine's airflow on your 2006–2007 Chevy Silverado or GMC Sierra 2500HD/3500HD with our comprehensive selection of LBZ Duramax intercooler and piping upgrades. The factory charged air system on the 6.6L LBZ features restrictive, pinched tubing and an intercooler with weak plastic end tanks that are prone to bursting under high boost. Furthermore, the factory rubber intercooler boots degrade over time and are notorious for blowing off under load, instantly robbing you of power when towing. Upgrading to a heavy-duty all-aluminum intercooler, paired with smooth, 3-inch mandrel-bent hot and cold side pipes, ensures your engine receives a massive volume of dense, cool air. This category is your central hub for all LBZ charged air upgrades, featuring dedicated subcategories for direct-fit intercoolers, high-flow intercooler pipe kits, and blowout-proof silicone boots with high-tension clamps. We supply premium cooling solutions from top-tier brands like Mishimoto, Banks Power, aFe Power, PPE, and CSF. Browse our complete inventory of 6.6L LBZ intercooler components below to securely lock down your boost and safely maximize your towing performance.
