Banks Power Boost Tube Upgrade Kit

2013–2018 RAM 2500/3500 6.7L Cummins

Part #: 25995

Overview

The Banks Power Boost Tube Upgrade Kit is engineered to dramatically improve airflow in your 2013–2018 RAM 2500/3500 equipped with the 6.7L Cummins engine. This kit replaces the restrictive factory boost tubes with larger 3.5-inch constant diameter mandrel-bent tubes, increasing the flow area by up to 103% compared to stock. Designed for diesel enthusiasts seeking enhanced turbo response and increased horsepower, these tubes optimize the path between the turbocharger, intercooler, and intake manifold for maximum efficiency and power gains.

By eliminating the factory hot side tube’s factory dent that reduces its diameter to just 2.25 inches, Banks Power’s upgrade kit restores and expands airflow capacity, allowing your engine to breathe better and deliver improved performance under boost. Whether you’re towing heavy loads or pushing your RAM for maximum power, this upgrade is a critical step toward unlocking your truck’s full potential.

Key Features

Designed with precision and durability in mind, the Banks Power Boost Tube Upgrade Kit offers the following key features:

• 3.5-inch constant diameter mandrel-bent tubes with larger radius bends for smooth airflow
• Up to 103% greater flow area compared to stock boost tubes, including factory dents
• Compatible with both the stock turbo elbow and the Banks Monster-Ram Gen 2 for enhanced performance
• High-quality aluminized steel construction for strength and corrosion resistance
• Red powder-coat finish on tubes for corrosion protection and improved grip during installation
• 4- and 5-ply heavy-duty high-temperature silicone couplers for superior sealing under high boost
• Spring-loaded constant tension clamps that maintain a secure, leak-free connection
• Improved intercooler efficiency and boost pressure retention for denser intake charge
• Lower exhaust gas temperatures (EGTs) contributing to engine longevity

Construction & Design

The Boost Tube Upgrade Kit is crafted from premium aluminized steel, chosen for its excellent heat resistance and durability in demanding under-hood environments. Each tube is mandrel bent to maintain a consistent 3.5-inch diameter throughout, eliminating airflow restrictions caused by sharp bends or dents found in the factory tubes. The larger radius bends reduce turbulence, promoting quicker turbo spool and more efficient boost delivery.

The tubes feature a red powder-coated finish that not only protects against corrosion but also stops short of the tube ends to provide a better grip surface for the silicone couplers. These couplers are constructed from multiple layers of heavy-duty silicone, designed to withstand high temperatures and pressures without failure. Spring-loaded constant tension clamps ensure a tight, reliable seal that prevents leaks and maintains boost integrity even under extreme conditions.

Performance & Sound

By significantly increasing airflow capacity, the Banks Power Boost Tube Upgrade Kit allows your turbocharger to spool faster and operate more efficiently. This results in improved throttle response, increased horsepower potential, and better overall engine performance. The enhanced boost retention between the turbo, intercooler, and intake manifold also contributes to lower exhaust gas temperatures (EGTs), promoting engine health and reliability during heavy towing or high-load scenarios.

Installation & Fitment

This kit is designed as a direct fit upgrade for 2013 through 2018 RAM 2500 and 3500 trucks equipped with the 6.7L Cummins engine. Installation is straightforward and requires no permanent modifications or special tools beyond standard hand tools. The kit works seamlessly with the factory turbo elbow and is also compatible with the Banks Monster-Ram Gen 2 elbow for those seeking maximum airflow improvements. The included silicone couplers and spring clamps ensure a secure, leak-free installation that maintains boost pressure under all driving conditions.

What's Included

• Left and right 3.5-inch mandrel-bent aluminized steel boost tubes (hot and cold side)
• 4-ply and 5-ply heavy-duty high-temperature silicone couplers
• Spring-loaded constant tension clamps
