The Cummins B Series is a straight-four and straight-6 diesel piston engine and is one of the most prolific engines for On and Off-Highway Markets.
The B6.7 is the latest version of the B Series. This is the largest light-duty straight-six engine that delivers 350 horsepower (261 kW; 355 PS) and 650 pound-feet (881 Nm) when used with a Chrysler-built six-speed 68RFE automatic transmission from the 2007.5 and newer Dodge 2500/3500 pickup trucks.
If they come with the Mercedes G56 6-speed manual transmission, the Cummins B6.7 will deliver 350 horsepower (261 kW; 355 PS) and 610 pound-feet (827 Nm).
For now, the Cummins 6.7L Turbo Diesel is the most powerful engine and is used in RAM 2500 and 3500 pickup trucks.
The latest model, 4th Gen 2016 is based on the MY 2013.5+ Cummins 6.7L Turbo Diesel. This model comes with Selective Catalytic Reduction (SCR) after treatment that uses Diesel Exhaust Fluid (DEF). This provides a 10 percent increase in fuel economy and is the best-in-class for 15,000-mile oil change intervals. You also get a new cooling system that delivers 25 percent more heat-rejection capacity. A high-efficiency fan, dual radiators, dual transmission coolers, and a charge-air cooler. The MY 2013.5+ engine is B20-capable and comes with a “smart” exhaust brake (Jake Brake).
Cold Air Intake Filters
Air filters are basic components engineered to prevent particulates from entering any parts where air and fluid flow. This includes the engine, radiator, and fuel lines. Air filters are integral parts of an engine’s live performance, as such, when a filter is not performing, the engine will deteriorate, and performance will falter.
Air filters are very basic units made of standard materials and designed to be changed within minutes. As a rule of thumb, air filters must be cleaned or changed at least once a year, or once every 12,000 miles, whichever comes first.
Filters do age, and also cleaning them or replacing them is a matter of common sense. If you drive in especially polluted areas such as construction sites, you should consider changing the filter after 6,000 miles.
Cold air intake filters are kits that provide over stock performance by increasing the flow of clean cold air to your engine. Just so you understand the impact of a cold air intake filter when compared to a stock, it will improve your acceleration by 11%, and a clean filter improves performance by the same degree. As such, you are looking at the improvement of up to 22% from a clogged stock air filter, when adding an aftermarket cold air filter.

The Best Cold Air Intakes for 6.7 Cummins Review and Buyer’s Guide:
1. Edge 39032-D & Evolution CTS2 Programmer
When you change your cold air intake filter you end up improving performance. However, you want to tweak that performance a bit more. So the guys and gals at Edge came up with this deal. Why just buy a cold air intake filter when you can buy a tuner with it too. The tuner will do everything the tuner is programmed to do; this includes reading and clearing all your DTC’s and providing tweaks via canned or custom tunes to improve performance in a vast array of functions.
I won’t go into the details of the tuner since this article is a review on cold air filters for 6.7 Cummins, but suffice it to say that the cost of this deal reflects the combined production costs in the package.
The tuner is compatible with Expandable Accessory System (EAS) and you canned tunes that deliver the following results:
Increase of 25 HP & 75 lb-ft, 45 HP & 145 lb-ft, 70 HP & 190 lb-ft., and 95 HP & 240 lb-ft
- Added Horsepower
- Added Fuel Economy
- Compatible with Edge Tuning Devices
- Enclose Housing for Increased Airflow
- Improves Continuous Power
- High Flow
- Dry Intake Filter
This deal is for the driver that wants to improve performance beyond the air filter, so if you are ready to take your Cummins into your hands and increase overall performance, this is the deal to get.
2. S&B Filters 75-5092 Cold Air Intake
The 75-5092 model is designed to improve airflow by 51.68%, thereby delivering better performance overall.
This model is made of silicone and not rubber, as such it can withstand temperatures of up to 400oF and will retain their grip of the couplers without fear of cracking, sliding or disconnecting.
The design features a secondary inlet that lowers the restriction level; this results in improved airflow and optimized performance.
The box is a one-piece integrated sealed device that is made of heat-resisting materials to maintain cooler air flow. It also comes with a MAF (Mass Air Flow) sensor that assures your check engine light remains off.
- Cotton Filter
- Red Oil
- 90 Grams Oil
A clean, cool unit, perfect for the 2012 6.7L Cummins applications.
3. S&B Filters 75-5068 Cold Air Intake Kit
The 75-5068 model is designed to improve airflow by 54.60%, thereby delivering better performance overall.
This model comes with an exceptionally efficient 8-layer cotton cleanable medium that provides maximum filtration qualities for high-performance results.
The body comes with swing gate pivots that operate in times of extreme heat, such as high load hauls or high altitude driving. These pivots open the ram-air duct mounted behind the grille and this releases cooler and less restrictive air into your engine.
This model is also made of silicone and not rubber, as such it can withstand temperatures of up to 400oF and will retain their grip of the couplers without fear of cracking, sliding or disconnecting.
This model features two inlets, and this pushes twice the air capacity, you can activate this option by removing the dam from the gate arm. If you are going to drive in polluted conditions, just re-attach the dam and revert to a single inlet.
- 8 Layer cotton filter
- Red oil
- 11 Grams Oil capacity
This is the best oil filter unit for 2013-2018 6.7L Cummin applications.
4. aFe Power Magnum FORCE 51-32413
