Banks Power Boost Tube Upgrade Kit

2013–2018 RAM 2500/3500 6.7L Cummins

Part #: 25994

Overview

The Banks Power Boost Tube Upgrade Kit is a direct OEM replacement for the left side boost tube (driver side, cold side) on 2013–2018 RAM 2500 and 3500 trucks equipped with the 6.7L Cummins engine. Designed for enthusiasts seeking enhanced performance and reliability, this upgrade significantly improves airflow through the intercooler system. By increasing the flow area by up to 67% compared to the stock tube, it reduces boost pressure loss, allowing your engine to breathe more efficiently and deliver maximum horsepower.

This boost tube is engineered to maintain higher air density from the turbocharger to the intake manifold, resulting in improved combustion and power output. Whether you are aiming for better towing capability, increased acceleration, or enhanced overall engine response, the Banks Boost Tube Upgrade Kit is built to meet the demands of serious horsepower applications.

Key Features

Designed to optimize airflow and boost retention, this upgrade kit offers several advanced features that set it apart from the factory boost tube:

• 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 superior flow
• 4- and 5-ply heavy-duty high-temperature silicone couplers for durability
• Spring-loaded constant tension clamps to maintain a secure, leak-free seal under high boost
• Red powder-coated finish on the tube body for corrosion resistance and enhanced grip
• Designed to work seamlessly with the Banks Monster-Ram Gen 2 for even greater airflow and faster turbo spool
• Improves cooling capacity and reduces exhaust gas temperatures (EGTs)

Construction & Design

The Banks Boost Tube Upgrade Kit is crafted from high-quality aluminized steel, chosen for its excellent corrosion resistance and heat tolerance. The tubes are mandrel bent to maintain a smooth, constant diameter throughout, eliminating restrictions and turbulence that can hinder airflow. This precise engineering ensures quicker turbo spool and more efficient boost delivery.

The red powder-coated finish not only protects the tube from environmental damage but also stops short of the tube ends to provide a better grip surface. This design detail ensures the included heavy-duty silicone couplers hold tight under extreme boost conditions without slipping or leaks. The spring-loaded constant tension clamps further enhance the reliability of the connection, preventing blown boots and maintaining consistent boost pressure.

Performance & Sound

By increasing the flow area and reducing boost pressure loss, the Banks Boost Tube Upgrade Kit helps your turbocharger spool faster and maintain higher boost levels. This results in improved throttle response, increased horsepower potential, and enhanced engine efficiency. Additionally, better airflow retention helps lower exhaust gas temperatures (EGTs), contributing to engine longevity and reliability under heavy load or towing conditions.

Installation & Fitment

This kit is designed as a direct OEM replacement for the left side boost tube on 2013–2018 RAM 2500 and 3500 trucks 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 spring-loaded clamps ensure a secure, leak-free installation that can withstand high boost pressures.

What's Included

• Mandrel-bent aluminized steel boost tube (3.5-inch diameter, left side/driver cold side)
• 4-ply and 5-ply heavy-duty high-temperature silicone couplers
• Spring-loaded constant tension clamps
• Red powder-coated finish on tube body

Ideal For

This upgrade kit is ideal for RAM 2500 and 3500 owners looking to maximize the performance of their 6.7L Cummins diesel engine. It is especially suited for those who tow heavy loads, participate in diesel performance events, or simply want to improve throttle response and horsepower without extensive modifications. Pairing this boost tube with the Banks Monster-Ram Gen 2 intake system unlocks even greater airflow and power potential.
