Banks Power Boost Tube Upgrade Kit

2013–2018 RAM 2500/3500 6.7L Cummins

Part #: 25996

Overview

The Banks Power Boost Tube Upgrade Kit is a direct OEM replacement for the left side boost tube (driver side, cold side) on 2013 to 2018 RAM 2500 and 3500 trucks equipped with the 6.7L Cummins engine. Designed for enthusiasts seeking serious horsepower gains, this upgrade significantly improves airflow through the intercooler system by offering a 67% greater flow area compared to the stock boost tube. By reducing boost pressure loss, the Banks Boost Tube allows more air and fuel to reach your engine, resulting in enhanced power output and improved throttle response.

This kit is ideal for those looking to maximize their turbocharged diesel engine’s performance without extensive modifications. It maintains higher air density from the turbocharger to the intake, supporting quicker turbo spool and better overall engine efficiency under high-boost conditions.

Key Features

The Banks Power Boost Tube Upgrade Kit combines advanced engineering and durable materials to deliver reliable performance improvements. Key features include:

• 67% greater cold side flow area than stock (3.5-inch diameter vs. 2.75-inch stock)
• Direct replacement for the left side boost tube (driver/cold side)
• Compatible with stock or aftermarket intercoolers with stock outlet size and location
• Mandrel-bent aluminized steel tubing with constant diameter for optimal airflow
• 4- and 5-ply heavy-duty high-temperature silicone couplers for secure connections
• Spring-loaded constant tension clamps to prevent leaks and blown boots under boost
• Red powder-coated finish on tube body for corrosion resistance and grip, with natural ends for coupler fitment
• Designed to work seamlessly with the Banks Monster-Ram Gen 2 for even greater airflow and turbo spool
• Improves cooling capacity and reduces exhaust gas temperatures (EGTs)

Construction & Design

The Boost Tube Upgrade Kit is crafted from premium aluminized steel, chosen for its excellent corrosion resistance and durability under high-heat conditions typical of turbocharged diesel engines. The tubing is mandrel bent to maintain a smooth, constant diameter throughout, eliminating airflow restrictions caused by sharp bends or diameter changes. This design ensures maximum flow efficiency and quicker turbo spool times.

The silicone couplers are constructed from heavy-duty 4- and 5-ply high-temperature materials, engineered to withstand the rigors of high boost pressures without cracking or leaking. The spring-loaded constant tension clamps maintain a tight seal even under extreme thermal expansion and contraction, ensuring reliable performance and preventing boost leaks.

Performance & Sound

By increasing the flow area by 67%, the Banks Boost Tube reduces boost pressure loss between the turbocharger and intake manifold. This results in a denser air charge reaching the engine, which supports higher horsepower and torque output. The improved airflow also contributes to quicker turbo spool, enhancing throttle response and overall drivability. Additionally, the enhanced cooling capacity helps lower exhaust gas temperatures (EGTs), promoting engine longevity and efficiency.

Installation & Fitment

This kit is designed as a direct OEM replacement for the left side cold side boost tube on 2013–2018 RAM 2500 and 3500 trucks equipped with the 6.7L Cummins engine. Installation requires no modifications and fits perfectly with the stock intercooler outlet size and location. The included silicone couplers and clamps ensure a secure, leak-free connection. For best results and maximum performance gains, it is recommended to combine this kit with the Banks Monster-Ram Gen 2 intake elbow.

What's Included

• 3.5-inch mandrel-bent aluminized steel boost tube (left side, cold side)
• 4- and 5-ply heavy-duty high-temperature silicone couplers
• Spring-loaded constant tension clamps
• Installation instructions

Ideal For

This upgrade kit is perfect for RAM 2500 and 3500 owners with the 6.7L Cummins engine who want to increase their truck’s horsepower and torque without extensive modifications. It suits diesel performance enthusiasts seeking improved turbo response, better boost retention, and enhanced cooling capacity. Whether used on stock or modified trucks, this boost tube upgrade supports higher power levels and improved engine efficiency.
