Banks Power 25990 Boost Tube Upgrade Kit for 6.7L Cummins

The Banks Power 25990 Boost Tube Upgrade Kit is engineered to maximize airflow and performance on 6.7L Cummins diesel engines. Featuring 3.5-inch diameter mandrel-bent aluminized steel tubing, these boost tubes deliver 40% greater flow area compared to the stock 2.73-inch tubes, allowing your turbocharger to spool up faster and maintain higher boost pressure throughout the system.

Key Features:

• Mandrel-bent aluminized steel construction maintains constant diameter for optimal flow
• 40% greater flow area than stock tubes reduces boost pressure loss
• Red powder-coated finish (stops before tube ends for secure coupler grip)
• 4-ply and 5-ply heavy-duty high-temperature silicone couplers
• Spring-loaded constant tension clamps prevent leaks and blown boots
• Compatible with stock intercooler or aftermarket units with stock inlet/outlet sizing
• Designed to work with Banks Monster-Ram intake (3.5" or 4") or stock elbow

Performance Benefits:

• Improved airflow increases horsepower and torque potential
• Faster turbo spool-up for better throttle response
• Greater cooling capacity helps lower exhaust gas temperatures (EGTs)
• Better boost retention between turbo, intercooler, and intake manifold
• Professional fit and finish for serious performance builds

This complete boost tube upgrade kit includes both hot-side and cold-side tubes with all necessary couplers and clamps for installation. The strategic powder-coat application ensures maximum grip where it matters most, while the heavy-duty silicone couplers and constant tension clamps maintain a leak-free seal even under high-boost conditions.
