Why It's Better

A True Monster Of A RAM

The all new Monster-Ram® intake for the 6.7L Cummins in your Ram lives up to its name. It is an absolute MONSTER. We pulled out all the stops when developing it.

Your Cummins engine struggles to breathe through its tiny, squashed stock inlet which causes boost loss at the same flow, while the Banks Monster-Ram® has a wide, unrestricted free-flowing path.

Stock versus Banks
Banks Monster-Ram intake manifold

The Monster-Ram® offers unparalleled airflow thanks to its custom-engineered fuel line.

All this without the need for tuning while being 50-state compliant.

Trusted by Tens of Thousands of RAM Owners


Since its debut in 2017, tens of thousands of RAM owners throughout the US and Canada have installed a Monster-Ram to prevent factory grid failure while enjoying quicker throttle response, improved fuel economy, and better drivability.

But performance means nothing without reliability

That's why Monster-Ram is engineered and tested to OEM-level standards. Every part in the Monster-Ram kit, including the proprietary fuel line, is covered by the Banks Limited Lifetime Warranty.



What It Does

The Monster-Ram® improves airflow from the intercooler. It flows 72.7 lbs/min with Banks’ New Coil Heater and High-Flow Cast Intake Plate compared to stock's 38.6 lbs/min MAF. That is a huge 88.3% improvement over stock you can feel!

The patented design raises boost without increasing back-pressure at the turbine. The result is improved engine response, efficiency, and headroom for daily driving and heavy hauling.

Chart of Flow versus Pressure Drop

It's All About
Mass Air Flow

The secret to the Monster-Ram®'s performance is not just airflow, but the quality and weight of the air it flows. Your Cummins engine is limited in the volume of air it can flow through its 6 cylinders even at max RPM.

By increasing the mass of the air delivered to each cylinder, your stock-tuned engine will breathe more efficiently with less stress, and set the stage for power gains when stacked with a tune.

Now Triple Heat Capable
Upgrade to 2250 Watts

The Monster-Ram® Kit includes a Banks 750-watt coil heater. Want more cold start heat?

Upgrade your Monster-Ram® to 2250 watts with the Triple Heater Upgrade Kit.

Triple Heat Capable
Billet Heater Upgrade

Need even more? 750-watt and 1500-watt billet heaters are also available for easy bolt-on supplemental starting heat.

Bolt-on up to an additional 1500W to your Single or Triple Heat Capable Monster-Ram®.


Cold Start Test Criteria

We followed RAM's cold start recommendations. Per the owner’s manual, RAM recommends the use of the block heater when the temperature drops below 0°F/-17°C and mandates the block heater at temperatures below -20°F/-29°C.

Using a controlled climate chamber, our first test utilized block heat and two Banks coil heaters (1500 watts total). The Monster-Ram® enabled our test truck to cold start down to -30°F/-34°C.

Against RAM’s recommendations, we also attempted to cold start with the same two coil heaters and no block heat. We were able to cold start down to -20°F/-29°C. Adding a third coil heater (2,250 watts total), the truck started at -30°F/-34°C.*

Cold Start Test Results

All tests were performed with two intake air pre-heat cycles per the owner’s manual. Intake air temperature is just one factor contributing to a successful cold start. Individual results may vary depending on your vehicle’s age and overall condition.

Prevents Broken Bolt Engine Failure

Cummins Ticking Time Bomb

Due to heat, vibration, and time, a stud and nut from the factory heater grid have been documented to come loose and fall into the intake manifold. Thanks to the engine's 5° rake, the broken bolt rolls downhill into cylinder #6, causing catastrophic failure that requires a complete engine rebuild or replacement from bent valves, damaged pistons, and head.

Broken bolt examples

Leaving Stock Heater
Chokes Performance

And, while you’re waiting for the BD screw to arc, melt, and fall into the intake manifold, the stock grid heater collects more soot and reduces airflow. Banks Monster-Ram® eliminates the grid heater. There’s nothing to fail or collect soot.

Banks versus stock

For peak performance, the Monster-Ram® includes a custom-machined high-flow cast intake plate. This plate is machined to the optimum thickness and features an oversized inlet CNC port-matched to the Monster-Ram® for zero restriction and maximum air density.


Unrivaled Airflow

Our engineers designed an all-new heating solution for the Monster-Ram®.

This new Banks exclusive coil heater sits vertically inside the Monster-Ram® without hindering airflow. This allows the factory grid heater to be replaced with the Banks High-Flow Intake Plate.

This eliminates the risk of engine failure due to parts loosening and falling into the engine while maintaining OEM-like cold weather engine start performance.

Bulletproof Reliability

Banks fuel lines are engineered to rigorous automotive quality-control standards using premium raw materials.

Each line is laboratory burst-tested to more than three times the maximum pressure produced by the factory high-pressure fuel pump, then fatigue-tested through 10 million pressure cycles simulating operation from idle to wide-open throttle.

Reviews

Peace of mind

"My bolt was still tight when I removed the grid heater but the peace of mind that it won’t be able to destroy my engine was reason enough to upgrade to the Banks monster ram. Install was pretty straightforward and can be done by anyone mechanically inclined and attention to details. I swear it added some additional power but I can’t be sure. I soon after added the pedal monster and iDash which really woke up throttle input."

Robert B. (5/5)

Great products!

"Install was not majorly difficult and the directions were spot on. Everything is working perfectly. I installed, the intake with grid heater upgrade, boost tubes and the ram air, cold air intake. Thank for making great products!"

Eric B. (5/5)

Difference in Acceleration

"I can feel the difference between the OEM Intake Acceleration and the Monster Ram Intake Acceleration. It is a great investment and upgrade to my 2017 Ram 3500 with only 127,000 miles on her. I also like the way the Monster Ram Intake brightens up the Engine Bay. Of all the failures, how many can be traced back to the owners NOT letting the Diesel Pre Heat cycle complete it's job."

Heather W. (5/5)

High Quality product

"The Banks product is a bit pricey, but very high quality. Requires a fairly skilled mechanic to install due to complexity and removal re-installation of high pressure fuel lines. Clean look and engine definitely seems to run stronger. And no more heater grid bolt concern."

Ben E. (5/5)

Must have

"Night and day difference. Intake, boost tubes, elbow and exhaust all done. The truck is deleted but this woke it up. The gas mileage average has gone up 5 MPG. The exhaust tip makes the sound deeper and getting rid of the grid heater helps me sleep at night. Great products! Well done."

Brent G. (5/5)

Monster RAM

"Took a little time to install. Instructions were awesome for the installation. Throttle response and acceleration seem to be better. Most of all the upgrade to eliminate the heating grid nut falling off into the cylinder."

Jay B. (5/5)

Great improvement

"I am a snowbird was south for the winter. Found Dave Auto in Utah and watched his video on the grid heater failure. I made an appointment at your Banks shop in California just before my trip home to Vernon BC, Canada. The improvement in boost from 15 to 30lbs. Made climb hills with 14,000 lb 5 wheel much easier. I also notice exhaust temperature was 100 degrees cooler. Plan to do the transmission pan and differential cover before my trip south this year. Dave"

David F. (5/5)

Banks heater grid delete

"My truck just turned 123000 mile and after reading what the consequences of not doing this upgrade I decided to do it. When my mechanic showed me my old grid heater, it was in good shape. But I certainly am glad I made the upgrade. No more worrying about the condition of the grid heater and definitely having the piece of mind knowing that the dreaded engine destroying grid bolt drop won’t take out my engine. Performance increase is incredible too!!! Can’t say enough about Banks Power! Thanks Gale!!"

Dave E. (5/5)

Must do upgrade

"Noticeable difference inhale response. The engine feels livelier through out the rev range. I opted for the multiple heater probes and have not had any cold start issues. Not terribly difficult to install. I also feel much better knowing I no longer have the bit of damoclese hanging over my engine waiting to cost me 15k (grid heater bolt, you tube it if you don’t know). Instructions provided were excellent, and you get a cool banks badge to put on your truck 15 out of 10 would recommend."

seth b. (5/5)

Monster relief

"Don’t let anyone talk you out of using Banks or convince you that the grid heater isn’t an issue. My neighbor had a ’22 Big Horn with 177K miles and dropped a bolt from the grid heater, which ended up killing his engine. I have a ’22 Laramie with 77K miles, and I’m relieved that I don’t have to worry about the grid heater issue anymore. I’m also happy that the grid heater itself is gone and that there’s more room for airflow, which should help reduce soot buildup. I’m not a mechanic by any means, but the installation was simple. Banks provided step-by-step instructions, and their customer support was there if I had any questions. The intake looks beautiful, too. I went with the red one, and it looks great under the hood. Overall, I’m extremely happy with the upgrade and, most importantly, I have peace of mind knowing I don’t have to worry about the grid heater anymore."

Q&A

I have a 2024 3500. After installing this product, does it make getting the fuel filter out harder? It’s difficult as is, thanks.
Monster-Ram should not interfere with fuel filter replacement.
Can I install this without needing to re tune the truck ?
Monster-Ram is designed to work on stock trucks with no tune, with standard emissions equipment.
I order the monster ram intake and i order it wrong! Looks like it does not fit my 2025 Ram 2500, is there a way to return it? Or exchange it for one that fits? Thank you
Hey thanks for messaging us, we have relayed this info over to our returns team, they will contact you with instructions via email on how to set up the return.
What about factory warranty? Does this affect my warranty?
The stance on aftermarket parts varies widely from dealer to dealer. This is why we suggest consulting with your dealer to learn how they choose to enforce Stellantis' warranty policies. Generally speaking, there are three types of dealerships. 1. Dealers that embrace and install performance upgrades. 2. Dealers who will overlook an aftermarket part because they know it's harmless. 3. Dealers who are militant about aftermarket accessories and will deny a warranty. You'll find dealers across the US and Canada that sell and install Monster-Rams. You'll also find dealerships that will encourage you to keep the vehicle stock. In the case of the Monster-Ram, keeping it, stock could prove to be a costly decision if the grid heater fails.
I have already bought the kit to delete and tune my ram 2500 2020 will this work with the delete kit?
We don't offer any products that can assist or tamper with emissions equipment.
