The tubing is mandrel bent to maintain a constant 3.5-inch diameter throughout its length, eliminating restrictions and turbulence that can occur with stock tubes. This smooth, consistent airflow path promotes faster turbocharger spool and improved boost retention.\u003c\/p\u003e\n\u003cp\u003eTo ensure a secure and reliable seal, the kit includes heavy-duty silicone couplers with multiple plies for enhanced strength and heat resistance. The powder-coat finish not only protects the tube but also stops short of the ends to provide a better grip surface for the couplers. Spring-loaded constant tension clamps further guarantee a leak-free connection, even under high boost pressures and thermal expansion.\u003c\/p\u003e\n\n\u003ch3\u003ePerformance \u0026amp; Sound\u003c\/h3\u003e\n\u003cp\u003eBy increasing the flow area and maintaining boost pressure more effectively, the Banks cold side boost tube helps your turbocharger spool faster and more efficiently. This results in improved throttle response and increased horsepower potential. Additionally, the enhanced cooling capacity helps reduce exhaust gas temperatures, contributing to overall engine longevity and performance stability. While primarily focused on airflow improvements, the upgrade may also contribute to a more responsive and aggressive turbo sound characteristic of high-performance diesel setups.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation \u0026amp; Fitment\u003c\/h3\u003e\n\u003cp\u003eThe Banks Boost Tube Upgrade Kit is designed as a direct OEM replacement for the driver side cold side boost tube on 2007–2009 Dodge Ram 2500 and 3500 trucks with the 6.7L Cummins engine.
