Banks Power Boost Tube Upgrade Kit

2010–2012 Dodge & RAM 2500/3500 6.7L Cummins

Part #: 25965

Overview

The Banks Power Boost Tube Upgrade Kit is engineered to significantly enhance the airflow efficiency of your 2010–2012 Dodge and 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 tubes on both the hot and cold sides, increasing flow area by up to 65% over stock. Designed for diesel enthusiasts seeking improved turbo response and horsepower gains, these tubes optimize the air path between the turbocharger, intercooler, and intake manifold.

Whether paired with the stock elbow or the Banks Monster-Ram intake system, this upgrade facilitates quicker turbo spool and better boost retention, resulting in enhanced engine performance and lower exhaust gas temperatures. The kit is ideal for those looking to maximize power output while maintaining reliable and durable operation under high-boost conditions.

Key Features

This boost tube kit offers a comprehensive set of features designed to improve airflow and durability:

• Up to 65% greater flow area compared to stock boost tubes (3.5" vs 2.75" hot side and 3" cold side)
• Mandrel-bent constant diameter tubing for smooth, unrestricted airflow
• Constructed from high-quality aluminized steel for corrosion resistance and strength
• Compatible with stock intercooler and aftermarket intercoolers with stock inlet/outlet sizes and locations
• Designed to work seamlessly with the Banks Monster-Ram intake system (3.5" or 4" versions)
• Heavy-duty 4- and 5-ply silicone couplers rated for high temperatures and boost pressures
• Spring-loaded constant tension clamps ensure secure, leak-free connections
• Available in natural aluminized finish or durable red powder coat for corrosion protection and style

Construction & Design

The Boost Tube Upgrade Kit features mandrel-bent aluminized steel tubes that maintain a constant 3.5-inch diameter throughout their length. This design eliminates airflow restrictions caused by diameter changes or sharp bends, promoting faster turbo spool and improved boost pressure retention. The aluminized steel construction offers excellent resistance to heat and corrosion, ensuring long-lasting durability in demanding diesel applications.

Couplers are crafted from multi-ply silicone designed to withstand high temperatures and pressures typical of boosted diesel engines. The spring-loaded constant tension clamps provide a secure grip that prevents leaks and blown boots, even under extreme boost conditions. The powder-coated option adds an extra layer of protection and a clean, professional appearance.

Performance & Sound

By increasing the boost tube diameter and improving airflow efficiency, this upgrade reduces turbo lag and lowers exhaust gas temperatures (EGTs). The enhanced airflow allows for more fuel delivery, translating into increased horsepower and torque potential. While the primary focus is on performance gains, the improved boost response also contributes to a smoother and more responsive driving experience without altering the engine’s sound signature.

Installation & Fitment

The Banks Power Boost Tube Upgrade Kit is designed for direct fitment on 2010 through 2012 Dodge and RAM 2500/3500 trucks equipped with the 6.7L Cummins engine. Installation is straightforward and requires no permanent modifications. The kit works with the stock elbow and intercooler setup or can be paired with Banks Monster-Ram intake systems for maximum performance gains. All necessary hardware, including silicone couplers and clamps, is included to ensure a secure and leak-free installation.

What's Included

• 3.5-inch aluminized steel hot side boost tube
• 3.5-inch aluminized steel cold side boost tube
• 4- and 5-ply heavy-duty silicone couplers
• Spring-loaded constant tension clamps
• Installation hardware and instructions

Ideal For
