The Cummins B Series is a straight-four and straight-6 diesel piston engines 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 engines life 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.
Now let’s take a look at the five best air filters for 6.7 Cummins engines.
