engine bay upgrade for 2001-2004 Chevrolet Silverado and GMC Sierra trucks equipped with the LB7 Duramax engine.\u003C\/p\u003E\u003Cp\u003EDesigned to replace and upgrade nearly every major airflow-related component, this comprehensive bundle improves intake airflow, charge-air flow, exhaust flow, cooling-system reliability, engine sound, performance, and under-hood appearance.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EWhat Is the HSP Deluxe Max Air Flow Bundle?\u003C\/strong\u003E\u003Cbr\u003EThe HSP Deluxe Max Air Flow Bundle includes a Hot Side Intercooler Tube, Factory-Style Cold Side Tube, Cold Air Intake, Max Flow Turbo Inlet Horn, Billet Thermostat Housing Kit, Replacement Up-Pipes, and Factory Replacement Coolant Tank.\u003C\/p\u003E\u003Cp\u003ETogether, these components reduce airflow restrictions, improve cooling-system durability, eliminate several common factory failure points, and provide a clean, coordinated appearance throughout the engine bay.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EHot Side Intercooler Tube\u003C\/strong\u003E\u003Cbr\u003EThe HSP Hot Side Intercooler Tube is manufactured from 3-inch mandrel-bent tubing and can provide up to 40% more airflow than the factory-style piping. Smooth, sweeping bends help reduce turbulence and restriction throughout the charge-air system.\u003C\/p\u003E\u003Cp\u003EA straight-style connection at the intercooler replaces the failure-prone factory lower intercooler boot configuration, creating a stronger and more reliable connection.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EMax Flow Turbo Inlet Horn\u003C\/strong\u003E\u003Cbr\u003EThe factory LB7 turbo inlet horn is a major restriction point in the intake system. The HSP Max Flow Turbo Inlet Horn features a smooth 3.5-inch design that improves airflow into the factory turbocharger while providing a cleaner and more refined appearance.\u003C\/p\u003E\u003Cp\u003EWhen combined with the included Cold Air Intake and upgraded intercooler piping, the inlet horn helps improve throttle response, turbo sound, and overall performance.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EBillet Thermostat Housing Kit\u003C\/strong\u003E\u003Cbr\u003EThe HSP Billet Thermostat Housing Kit relocates the coolant hose that normally runs over the driver\u0027s-side valve cover. This opens up the engine bay, improves access to surrounding components, and provides additional room for high-pressure fuel pump upgrades.\u003C\/p\u003E\u003Cp\u003EThe billet construction also delivers a cleaner and more durable replacement for the factory-style thermostat housing components.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EFactory-Style Cold Side Tube\u003C\/strong\u003E\u003Cbr\u003EThe HSP Factory-Style Cold Side Tube is manufactured from 3-inch mandrel-bent tubing to increase airflow capacity compared to the restrictive factory piping.\u003C\/p\u003E\u003Cp\u003EIts smooth bends help reduce turbulence and maintain efficient airflow through the charge-air system, supporting improved throttle response, turbo spool-up, and overall engine performance.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003E2-Inch Replacement Up-Pipes\u003C\/strong\u003E\u003Cbr\u003EThe HSP Replacement Up-Pipes are constructed from heavy-wall 304 stainless steel and feature sleeved bellows designed to withstand extreme exhaust temperatures, vibration, and repeated heat cycles.\u003C\/p\u003E\u003Cp\u003EThese 2-inch up-pipes improve exhaust flow while addressing common factory up-pipe failure points. The included ceramic coating provides additional heat management and durability.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EFactory Replacement Coolant Tank\u003C\/strong\u003E\u003Cbr\u003EThe HSP Factory Replacement Coolant Tank replaces the factory plastic reservoir with a fully welded, all-metal tank. Unlike the factory tank, the HSP replacement is resistant to cracking, discoloration, and deterioration caused by years of engine bay heat.\u003C\/p\u003E\u003Cp\u003EThe tank includes the required fittings, radiator cap, and low-coolant sensor. It is also available in multiple powder coat options to coordinate with the rest of the engine bay.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ECold Air Intake\u003C\/strong\u003E\u003Cbr\u003EThe HSP Cold Air Intake features a 4.5-inch mandrel-bent intake tube designed to maximize airflow into the turbocharger.
