Unboxing the Banks Monster-Ram feels like receiving a serious performance part. The packaging is secure and professional. Inside, you’ll find everything needed for the installation aside from basic hand tools and a torque wrench. The centerpiece is the composite intake manifold itself, which is noticeably larger and more substantial than the stock piece. The integrated Killer Grid Heater is already mounted. Banks also includes a complete set of high-quality gaskets (both intake manifold and grid heater gaskets) and all necessary bolts and hardware. The instructions are detailed and include helpful diagrams. The build quality is immediately apparent, with clean casting and robust fittings. There are no missing items, but you will need a fresh bottle of coolant for the grid heater loop and possibly new intake horn gaskets depending on your truck’s configuration. This completeness makes tackling the Banks Monster-Ram vs stock intake replacement a more confident project.

Before turning a wrench, ensure you have a clean, well-lit workspace. Gather all necessary tools: metric socket set, torque wrench, screwdrivers, pliers, and a drain pan. Disconnect the negative battery cable. This is a 3-5 hour job for a competent DIYer. Begin by draining a small amount of coolant from the grid heater coolant lines (clamp and disconnect). Then, methodically remove the intake horn, associated piping, wiring harnesses, and sensors connected to the stock intake manifold. Labeling connectors with tape can be helpful. The core question of should I buy Banks Monster-Ram often hinges on install difficulty, but with patience, it’s very manageable.
Once everything is disconnected, unbolt and carefully remove the stock intake manifold and grid heater as an assembly. Take this time to thoroughly clean the cylinder head surface where the new manifold will seat. Any debris left behind is a potential leak point. Compare the stock manifold to the Banks unit—the difference in runner size and plenum volume is striking and visually answers why this Monster-Ram Intake upgrade for Cummins is effective.
Install the new grid heater gasket and intake manifold gasket onto the cylinder head. Carefully lower the massive Banks Monster-Ram assembly into place. Hand-thread all the new supplied bolts. Following the provided torque sequence and specification is critical to prevent leaks and ensure even clamping force. This step is where the precision of the kit shines.
Reconnect all sensors, wiring harnesses, and the coolant lines to the new Killer Grid Heater. Reinstall the intake horn and all air piping. Refill the coolant system, ensuring you bleed any air from the grid heater circuit. Reconnect the battery. Double-check all connections before starting the engine.
On first start, the engine may crank slightly longer as the system primes. Listen for any obvious air leaks (a distinct whistling or hissing). Once idling, check for coolant leaks at the grid heater connections. Take the truck for a gentle drive to bring it to operating temperature and monitor gauges. The immediate seat-of-the-pants difference is often a stronger, smoother idle.
Maintenance is minimal. Periodically inspect the manifold and connections for tightness, especially after the first few heat cycles. When servicing your air filter, give the intake horn and visible parts of the manifold a visual inspection. For more detailed care tips on your entire intake system, see our diesel intake maintenance guide.

We installed the Banks Monster-Ram on a 2022 Ram 2500 Cummins with otherwise stock powertrain. Testing occurred over three weeks and 1,200 miles, encompassing daily driving, highway cruising, and heavy towing (a 14,000 lb equipment trailer). We used an OBD-II scanner to monitor key parameters like boost, drive pressure, and calculated engine load, and relied on butt-dyno feel and fuel economy tracking.
The most notable metric was the reduction in drive pressure (backpressure) relative to boost. Pre-install, the truck would often see drive pressure exceed boost by 5-8 psi under heavy throttle. Post-install, that differential shrunk to just 1-3 psi. This validates Banks’ claim of raising boost efficiently. Throttle response became noticeably sharper, with reduced turbo lag off the line. The engine also felt smoother throughout the RPM range.
During towing, the benefit was clearest. Merging onto highways or climbing grades required less throttle input to maintain speed. The engine felt less strained, and exhaust brake effectiveness seemed improved due to the better-flowing path. In daily driving, the truck felt more eager and responsive, making it more enjoyable to drive empty. This real-world performance is a core part of determining if the Banks Monster-Ram Intake is worth it for you.
Banks’ claims of improved flow and efficiency held true in our testing. We did not achieve dramatic peak horsepower gains (as expected on a stock tune), but the area-under-the-curve improvement was significant. The advertised “bolt-on” nature was accurate, though the installation requires mechanical confidence. For the right user, it delivers exactly as promised, solidifying its position as a top contender for the best intake for Ram 2500 6.7L.
How does the Banks stack up against other options like the S&B Cold Air Intake or the stock intake with a aftermarket filter? The key difference is that the Monster-Ram replaces the restrictive manifold itself, while most “intakes” only replace the airbox and filter.
