5 6.7 Cummins Upgrades Options — Fitment and Buying Notes
1. Banks Monster-Ram 42799-B, 2019–2024
A black-finished intake and grid-heater replacement package for manufacturer-listed 2019–2024 Ram 2500/3500 6.7L pickups. Banks excludes chassis-cab trucks from this version. Confirm 42799-B, the fuel-line configuration and current emissions documentation for the exact truck.
Key Features That Stand Out
- ✓ Design: An intake elbow with the associated heater/plate upgrade.
- ✓ Details: The manufacturer lists an upgraded fuel line in the package.
- ✓ Application: A generation-specific kit rather than a universal intake horn.
Why We Recommend It
This is a substantial mechanical project, not the first purchase for an undiagnosed drivability problem. The useful reason to compare it is the matched intake and heater package. Review the installation guide, engine condition and required labor before ordering.
Performance Analysis
This is an editorial assessment of the listed design and application, not a hands-on test. A complete, identifiable intake/heater package with manufacturer documentation. Installation is involved and the chassis-cab exclusion matters; advertised gains are not guaranteed on your truck.
Best For
A documented intake/grid-heater project on a matching 2019–2024 pickup. Banks excludes chassis-cab trucks from this version. Confirm 42799-B, the fuel-line configuration and current emissions documentation for the exact truck.

2. Banks Monster-Ram 42798, 2013–2018
The earlier-generation Monster-Ram intake and heater package listed for 2013–2018 Ram 2500/3500 6.7L pickups. The 42798 application differs from 42799-B. Verify the exact kit, pickup versus chassis cab, finish and current installation instructions.
Key Features That Stand Out
- ✓ Design: A separate 2013–2018 application.
- ✓ Details: An intake and grid-heater upgrade package.
- ✓ Application: A documented kit number for matching components.
Why We Recommend It
This card exists to keep earlier trucks separate from the 2019+ recommendation. Choose it only when the manufacturer catalog matches the truck and the shop agrees with the project scope. A later-generation part should not be substituted because the engine displacement matches.
Performance Analysis
This is an editorial assessment of the listed design and application, not a hands-on test. A defined kit for an earlier Cummins generation. It is not interchangeable with the 2019–2024 kit and requires careful installation planning.
Best For
An older 6.7L pickup with a confirmed 42798 application. The 42798 application differs from 42799-B. Verify the exact kit, pickup versus chassis cab, finish and current installation instructions.

3. Mopar Filter Bundle, Seller-Listed 2020–2024
An Amazon-listed bundle of fuel/water-separator, fuel and engine-oil filters advertised for 2020–2024 Ram 2500/3500 6.7L diesel trucks. Compare every included part number with the Mopar VIN catalog and inspect the seller and packaging. A bundle title is not proof of authenticity or fit for a different year.
Key Features That Stand Out
- ✓ Design: Fuel/water-separator filter in the advertised bundle.
- ✓ Details: Fuel filter in the advertised bundle.
- ✓ Application: Engine-oil filter included as a maintenance group.
Why We Recommend It
Correct maintenance can be more useful than buying a modification to mask a fault. This bundle is convenient only if all the parts match the VIN. Verify seller authenticity and included numbers before relying on the listing’s genuine-OEM description.
Performance Analysis
This is an editorial assessment of the listed design and application, not a hands-on test. Several scheduled-maintenance items grouped into one listing. Seller authenticity and each part number need checking; maintenance is not a horsepower upgrade.

4. ANCEL HD3400 Pro Diagnostic Tool
An Amazon-listed commercial-diesel scanner to consider when diagnostics, rather than another engine part, is the priority. Confirm the precise 6.7L vehicle and functions in writing. Commercial Cummins coverage is not automatic enhanced Ram pickup coverage.
Key Features That Stand Out
- ✓ Design: Diesel and standard OBD-II diagnostic modes.
- ✓ Details: Supported live-data and fault-report functions.
- ✓ Application: Heavy-duty connector/application support advertised by the seller.
Why We Recommend It
Treat this as a diagnostic equipment upgrade. A recorded fault and live-data check can prevent buying an intake or filter bundle for the wrong problem. For a Ram pickup, demand a year-and-function coverage report before purchase.
Performance Analysis
This is an editorial assessment of the listed design and application, not a hands-on test. A dedicated diagnostic workflow that can guide the repair decision. Not a power modification; advanced Ram functions depend on confirmed coverage.
Best For
Diagnosing a confirmed supported Cummins application before buying parts. Confirm the precise 6.7L vehicle and functions in writing. Commercial Cummins coverage is not automatic enhanced Ram pickup coverage.

5. K&N 63-1584 Intake, 2019–2024 6.7L
An enclosed-air-box intake with an HDPE tube and reusable oiled-cotton filter for listed 2019–2024 Ram 2500/3500 6.7L applications. K&N states this part is not legal for sale or use in California on pollution-controlled vehicles. Verify exact fitment and local emissions requirements before ordering.
Key Features That Stand Out
- ✓ Design: Enclosed air box with an accessible filter lid.
- ✓ Details: Roto-molded HDPE intake tube.
- ✓ Application: A reusable oiled-cotton filter requiring correct servicing.
Why We Recommend It
Compare this by filter-maintenance preference, enclosure design and installation scope. An oiled reusable filter needs correct cleaning and oiling. Do not buy it for a prohibited location or expect the maker’s dyno example to guarantee a towing or fuel-economy result.
Performance Analysis
This is an editorial assessment of the listed design and application, not a hands-on test. A defined intake package and reusable filter design. California restriction and filter-care requirements are material buying limitations.
Best For
An intake change where the application and local rules permit this exact part. K&N states this part is not legal for sale or use in California on pollution-controlled vehicles. Verify exact fitment and local emissions requirements before ordering.

Complete Buying Guide for Best 6.7 Cummins Upgrades
Choose the right 6.7 Cummins upgrades for the job and the exact application. The options above are research starting points; verify current fitment with the manufacturer before buying.
Essential Factors We Consider
A 2025-and-newer Cummins is a different application from many 2019–2024 catalog parts. Start with fault codes, maintenance, and towing temperatures. Separate airflow changes from routine filters and transmission-service parts.
- Exact year, engine, trim and vehicle configuration
- Manufacturer-listed application and installation requirements
- Real benefit for the intended use and known limitations
- Warranty, safety, legal and maintenance implications
Budget Planning
An intake manifold has more labor and fitment risk than a filter service. Include installation, required hardware, and emissions documentation in the price comparison.
Final Thoughts
For a working truck, reliable service and useful monitoring are sensible first steps. Add a year-specific intake or exhaust only when it addresses a defined need.
Frequently Asked Questions
Q: What are the most common issues with the 6.7 Cummins that upgrades can address?
Start with diagnosis and maintenance. An intake or exhaust only makes sense when its current manufacturer listing matches your truck and goal.
Q: Will installing these 6.7 Cummins upgrades void my truck’s warranty?
Warranty coverage depends on the failure and the modification. Ask the manufacturer or dealer about the exact part and retain installation records.
Q: How often should I replace filters on my 6.7 Cummins, and does the OEM bundle help?
Use the Ram/Cummins maintenance schedule and VIN-matched filter numbers. A filter bundle is maintenance, not a performance claim.
Q: Do performance upgrades for the 6.7 Cummins always improve fuel economy?
No. Fuel economy varies with load, driving, calibration, and maintenance; do not assume a gain from an intake or exhaust.
Q: Are the transmission upgrades for the 6.7 Cummins easy to install myself?
Installation complexity varies. A manifold or exhaust can require professional tools and emissions checks; read the kit instructions first.
Q: What is the benefit of a steel heater hose connector over the OEM plastic one?
A replacement connector addresses a specific repair need, not a general power upgrade. Diagnose a leak before ordering.
Q: Why is improved transmission cooling important for the 6.7 Cummins?
Transmission temperature matters under load, but select any cooling change only after checking the transmission, service procedure, and exact fitment.
