Designed to replace and upgrade nearly every airflow-related component, this bundle is built to maximize performance and visual appeal.\u003c\/p\u003e\n\u003ch3\u003eWhat Is the HSP Diesel Deluxe Max Air Flow Bundle?\u003c\/h3\u003e\n\u003cp\u003eThis bundle includes everything HSP offers for LB7 Duramax performance upgrades: hot and cold side intercooler tubes, a stock turbo inlet horn, billet thermostat housing kit, replacement up-pipes, a replacement coolant tank, and a cold air intake. Together, these parts provide significant gains in power, cooling efficiency, and under-hood aesthetics.\u003c\/p\u003e\n\u003ch4\u003eHot Side Intercooler Tube\u003c\/h4\u003e\n\u003cp\u003eThis tube has been increased to a 3\" diameter, offering up to 40% greater flow. Mandrel-bent sweeping curves reduce turbulence, while a straight-style intercooler connection eliminates a known factory failure point.\u003c\/p\u003e\n\u003ch4\u003eStock Turbo Inlet Horn\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the stock turbo, this upgraded 3.5\" inlet horn removes restrictive bottlenecks and delivers more power.

It's functional and visually cleaner.\u003c\/p\u003e\n\u003ch4\u003eCold Side Tube\u003c\/h4\u003e\n\u003cp\u003eAlso upgraded to 3\" diameter, the cold side tube features smooth mandrel bends for efficient airflow and reduced heat.
