Banks Power 25993 Boost Tube System

The Banks 25993 Boost Tube System will get the turbo spooling faster in your GM Silverado/Sierra 2500HD/3500HD 6.6L Duramax LML. These higher-flowing tubes retain more boost pressure between the turbo, intercooler, and intake which results in maximum horsepower. The included 4 and 5-ply heavy-duty silicone couplers combined with spring-loaded constant tension clamps for a tight, reliable hold under high boost conditions. Banks hot and cold side tubes are constructed from a high-quality mandrel bent 3.5" aluminized steel tube for a smooth constant diameter for quicker spool up. These better-flowing intercooler tubes result in less boost pressure loss from the turbo to the intake manifold and have up to 105% greater flow area versus the factory tubes. This results in less work for the turbocharger, improving power consistency and engine efficiency. These tubes are compatible with stock or aftermarket intercoolers with stock inlet & outlet size and location.
