2010-2012 Cummins Boost Tube Upgrade Kit (259XX)

Fits

Experience the upgraded Banks Monster-Ram for the 6.7L Cummins - it's bad-ass! Boasting larger boost tubes compared to stock and compatible with stock elbows or the new Monster-Ram (3.5" or 4"), enjoy improved airflow and faster turbocharger spool-up speed.

Banks cold side tubes boast a 37% larger flow area compared to stock tubes. Made from high-quality aluminized steel, these tubes are mandrel bent and have a consistant diameter, resulting in faster turbo spool. The improved flow of intercooler tubes helps retain boost pressure (increasing density) between the turbo, intercooler, and intake for maximum horsepower. Banks tubes come in either a sleek red or natural finish, stopping before the end for better grip and reinforced by heavy-duty high-temperature silicone couplers, ensuring a tight hold even under high-boost conditions. Banks spring-loaded constant tension clamps provide a stronger grip and prevent any leaks or blown boots.
