Banks Power 25991 Cold-Side Boost Tube Upgrade Kit for 6.7L Cummins

The Banks Power Cold-Side Boost Tube Upgrade Kit is engineered for 6.7L Cummins diesel engines equipped with the Banks Monster-Ram intake system. This performance-oriented upgrade replaces the factory boost tube with a larger 3.5-inch diameter mandrel-bent aluminized steel tube that delivers 40% greater flow area than the stock 2.73-inch tube.

Key Performance Benefits:

• 3.5-inch diameter provides 40% more flow area than factory 2.73-inch tube
• Mandrel-bent construction maintains constant diameter for unrestricted airflow
• Enables faster turbocharger spool-up and improved boost pressure retention
• Reduces boost pressure loss between turbo, intercooler, and intake manifold
• Helps lower exhaust gas temperatures (EGTs) under load
• Maximizes horsepower potential when paired with Banks 3.5" or 4" Monster-Ram

Construction and Quality:

• High-quality aluminized steel construction with gray powder-coat finish
• Powder coating stops before tube ends for superior coupler grip
• Includes 4-ply and 5-ply heavy-duty high-temperature silicone couplers
• Spring-loaded constant tension clamps prevent leaks and blown boots under high-boost conditions
• Driver-side cold-side tube only (turbo to intercooler)

This kit is designed to work with stock or aftermarket intercoolers featuring stock-sized inlet and outlet connections. Precision-engineered for perfect fitment and built for serious horsepower applications, the Banks boost tube upgrade is an essential component for maximizing the performance of your 6.7L Cummins diesel engine.
