Banks Power Boost Tube Upgrade Kit

Fits Most Dodge/Ram 6.7L Diesel/5.9L Diesel (10-12)

Part #: 25998

Overview

The Banks Power Boost Tube Upgrade Kit is engineered to significantly enhance airflow in your 2010–2012 Dodge and RAM 2500/3500 equipped with the 6.7L Cummins engine. This kit replaces the restrictive factory boost tubes with large 3.5-inch constant diameter mandrel-bent tubes on both the hot and cold sides, increasing flow area by up to 65%. Designed for diesel enthusiasts seeking improved turbo response and horsepower gains, these tubes work seamlessly with the stock elbow or the Banks Monster-Ram intake system.

By allowing more air to flow through the turbocharger and intercooler system, the Banks boost tubes enable your engine to breathe better, supporting increased fuel delivery and resulting in more power and quicker turbo spool. This upgrade is ideal for those looking to maximize performance while maintaining reliability and fitment with stock or aftermarket intercoolers.

Key Features

This boost tube kit offers a substantial upgrade over the factory components, delivering improved airflow and durability:

• Up to 65% greater flow area compared to stock boost tubes (3.5" vs. 2.75" and 3")
• Mandrel-bent aluminized steel construction for consistent diameter and smooth airflow
• Red powder-coated finish on tubes for corrosion resistance and enhanced grip
• Heavy-duty 4- and 5-ply high-temperature silicone couplers for secure, leak-free connections
• Spring-loaded constant tension clamps maintain tight seals under high boost pressure
• Compatible with stock intercooler or aftermarket intercoolers with stock inlet/outlet size and location
• Designed to work with stock elbow or Banks Monster-Ram intake systems (3.5" or 4")
• Improves turbocharger spool time and boost retention for maximum horsepower potential

Construction & Design

The boost tubes are crafted from high-quality aluminized steel, chosen for its excellent heat resistance and durability in demanding under-hood environments. The mandrel bending process ensures a constant diameter throughout the tube length, eliminating restrictions and turbulence that can reduce airflow efficiency. The red powder-coat finish not only protects the tubes from corrosion but also stops short of the tube ends to provide a better grip surface for the silicone couplers.

Couplers are constructed from multi-ply silicone designed to withstand high temperatures and pressures typical of boosted diesel applications. The spring-loaded constant tension clamps maintain a secure, leak-free connection even under extreme boost conditions, preventing the common issue of blown boots or leaks that can compromise performance.

Performance & Sound

By increasing the diameter and smoothing airflow through the boost tubes, this upgrade reduces turbo lag and improves spool time, allowing the turbocharger to reach optimal boost levels faster. Enhanced airflow also contributes to better intercooler efficiency and boost pressure retention, which can lead to lower exhaust gas temperatures (EGTs) and improved engine responsiveness. While primarily focused on performance gains, the kit maintains the factory sound profile without introducing unwanted noise.

Installation & Fitment

The Banks Power Boost Tube Upgrade Kit is designed for a direct bolt-on installation on 2010 through 2012 Dodge and RAM 2500/3500 trucks equipped with the 6.7L Cummins engine. No modifications are required when used with the stock elbow or Banks Monster-Ram intake systems. The kit fits both stock and compatible aftermarket intercoolers with standard inlet and outlet sizes and locations, making it a versatile upgrade for a variety of setups.

Installation can typically be completed with basic hand tools and does not require specialized equipment, making it accessible for experienced DIY enthusiasts or professional installers.
