Bulletproofing a 2016 Dodge Cummins 3500: The Ultimate Banks Power Upgrade

When it comes to heavy-duty towing, reliability is everything. If you're driving a 2007.5 to 2024 Dodge Cummins, you already know these engines are absolute workhorses. However, even the toughest factory setups have a few hidden vulnerabilities—and if you are running a stock, emissions-on truck, keeping things clean and efficient is vital to the life of your engine.
We recently had a 2016 Dodge Cummins 3500 come into the Power Forge Diesel garage for a full charge-side upgrade. The goal? Maximize fuel economy, boost power, and take care of a ticking time bomb known as the "killer" grid heater nut before it could cause catastrophic engine failure.
To get the job done right, we went with a complete, top-of-the-line Banks Power system.
The "Killer" Grid Heater Nut: Why the Factory Intake Elbow Has to Go
If you own a modern 6.7L Cummins, you need to know about the factory grid heater issue. Over time, the electrical connection on the stock grid heater can degrade due to heat cycling and vibration. The retaining nut on the bottom of the grid heater can loosen up, jiggle free, and drop straight into the intake manifold.
The Risk: If that small metal nut gets sucked into cylinder number 6, it will completely destroy your engine, leaving you with thousands of dollars in damages.
We stripped the system down to the intake plenum to eliminate this risk entirely. By installing the Banks Monster-Ram Intake Elbow, we didn't just massively increase airflow—we permanently removed that factory failure point. It is an absolute must-do upgrade for any 2007.5–2024 Cummins owner who wants peace of mind while hauling heavy loads through the Arizona heat.
Unrestricted Airflow: The Complete Banks Charge-Side System
To complement the new intake elbow and extract maximum efficiency from this stock emissions truck, we didn't stop at the horn. We upgraded the entire charge-air assembly:
Banks Boost Tubes: The factory hot and cold-side tubes are restrictive and prone to leaking under high boost pressures. The rugged, mandrel-bent Banks boost tubes maximize flow area and maintain solid pressure.
Banks Techni-Cooler Intercooler: The Yuma desert puts massive thermal strain on your engine. The heavy-duty Banks intercooler features thicker, more efficient cores and redesigned end tanks. This drops intake air temperatures drastically, packing denser, oxygen-rich air into the cylinders.
Better Fuel Economy, More Power, Total Reliability
Hard to beat this setup on a stock emissions truck. By reducing pumping losses and optimizing how the engine breathes, the owner of this Cummins 3500 will see improved throttle response, lower exhaust gas temperatures (EGTs), better fuel mileage, and a much cleaner combustion cycle.
Whether this truck is pulling agricultural equipment around Yuma or hauling a massive fifth-wheel across the desert, it is now built to handle the workload reliably.
