Banks Power Boost Tube Upgrade Kit

2007–2009 Dodge Ram 2500/3500 6.7L Cummins

Part #: 25990

Overview

The Banks Power Boost Tube Upgrade Kit is a direct OEM replacement designed to enhance the airflow efficiency of your Dodge Ram 2500 or 3500 equipped with the 6.7L Cummins engine from 2007 to 2009. This kit includes both left and right side boost tubes with heavy-duty silicone couplers, engineered to provide a 40% greater flow area compared to the stock tubes. By reducing boost pressure loss, these tubes allow more air and fuel to reach your engine, resulting in improved horsepower and throttle response.

Ideal for diesel enthusiasts seeking serious horsepower gains, the Banks Boost Tubes maintain higher air density from the turbocharger to the intake manifold. This upgrade supports quicker turbo spool and better overall engine performance without requiring modifications to the stock intercooler setup.

Key Features

Designed to maximize airflow and boost retention, this kit offers several performance-enhancing features:

• Complete set of hot and cold side boost tubes for both left and right sides
• 3.5-inch constant diameter tubing versus stock 2.73-inch diameter for superior flow
• Mandrel-bent aluminized steel construction ensures smooth, consistent airflow
• 40% greater flow area compared to factory tubes to reduce boost pressure loss
• 4- and 5-ply heavy-duty high-temperature silicone couplers for durability under high boost
• Spring-loaded constant tension clamps maintain secure connections and prevent leaks
• Powder-coat finish stops short of tube ends to provide better grip for couplers
• Compatible with stock intercooler or aftermarket intercoolers with stock inlet/outlet size and location
• Works seamlessly with Banks Monster-Ram Gen 2 elbow for even faster turbo spool and improved airflow
• Helps lower exhaust gas temperatures (EGTs) and increases cooling capacity

Construction & Design

Each boost tube is crafted from high-quality aluminized steel, chosen for its excellent heat resistance and durability in demanding under-hood environments. The tubes are mandrel bent to maintain a constant diameter throughout their length, eliminating restrictions and turbulence that can reduce airflow efficiency. This precise engineering supports quicker turbo spool and sustained boost pressure.

The silicone couplers are constructed with multiple plies to withstand high temperatures and pressures typical of boosted diesel applications. The spring-loaded constant tension clamps ensure a tight, leak-free seal even under extreme boost conditions. The powder-coat finish not only protects the tubes from corrosion but also stops short of the ends to provide a secure grip for the couplers, preventing slippage or blown boots.

Performance & Sound

By increasing the flow area by 40%, the Banks Boost Tubes reduce boost pressure loss between the turbocharger and intake manifold. This results in more dense air delivery, allowing the engine to burn more fuel efficiently and produce maximum horsepower. The improved airflow contributes to quicker turbo spool, enhancing throttle response and overall drivability. Additionally, better boost retention helps lower exhaust gas temperatures, promoting engine longevity and reliability.

Installation & Fitment

The Banks Boost Tube Upgrade Kit is designed as a direct fit replacement for the 2007–2009 Dodge Ram 2500 and 3500 with the 6.7L Cummins engine. Installation requires no modifications and can be completed using standard hand tools. The kit works with the stock intercooler or aftermarket intercoolers that maintain the factory inlet and outlet size and location. For those seeking further performance gains, the kit is fully compatible with the Banks Monster-Ram Gen 2 elbow upgrade.

What's Included

• Left and right side hot and cold side boost tubes (3.5-inch diameter)
