Product Description & Performance

For various reasons, S&B 75-5092 is the best cold air intake for 6.7 Cummins. It boosts airflow by an average of 50% and keeps your engine cooler than ever before. This 6.7 Cummins cold air intake has an incredible efficiency rate of 99.5%.

You don’t have to worry about your engine’s efficiency for a year because this filter enhances it by keeping dust and debris from entering.

“It is built following the ISO-5011 standard. Its quality and performance are unquestionable. Since this air filter enhances airflow, your engine’s performance improves as well.”

To increase the airflow, S&B oiled cotton filters are made up of 8 layers of cleanable media. They employ pleats that are deeper and broader, with more pleats per filter. Furthermore, their manufacturing technique produces filters with virtually slight “bleed,” resulting in a larger exposed surface area.

All of this adds up to greater filter surface area, which equals more airflow and better protection. Washable and reusable, S&B cotton air filters protect your engine from hazardous dirt and debris.

Silicone components are used in the construction of this Cummins to ensure durability and endurance. S&B is the finest cold air intake brand since every filter is pre-oiled with 90 grams of oil before shipping.

Under the hood, your rig will acquire not just performance but also a sporty, high-tech look. Furthermore, the filters and couplers are constructed of silicone rather than urethane, which means they won’t deteriorate or break and can withstand temperatures up to 400 degrees Fahrenheit. Above all, this intake system has a distinctive transparent lid that allows for constant visual examination of your filter.

Buying consideration: Best Cold Air Intake for 6.7 Cummins

Cold air intake systems can make a real difference to your vehicle. Filtering and enhancing the quality of air flowing to the Cummins diesel engine will surely improve the performance. Thus, you need to take proper time choosing the best quality product. Here are the considerations you need to think of when choosing the best cold air intake for 6.7 Cummins.

Inlet tube

The inlet tube size has to do with the horsepower and by extension, the overall engine performance. The wider the tube is, the more air it will allow inside the engine. More air means more oxygen which then means a faster combustion process.

Also, the best air intake systems have a heat insulation mechanism that cools the air flowing to the engine. Some cold air intake systems come with a heat shield covering the whole air filter and inlet tube. Others have insulated tubes or both mechanisms at the same time.

The inlet tubes’ material also differs in the performance of the engine. Usually, tubes come in three different materials; either silicone, aluminum, or rubber.

The most common material is Silicone as it offers much expandability and heat insulation. So, it functions the best among the other two materials.

Later comes aluminum is a durable material but it conducts heat. Thus, they always come with a heat shield or so to prevent overheating.

Finally, rubber, which is the least durable material of the three. In spite of its expandability and flexibility, it is not the best in terms of quality.

Horsepower & throttle response

Both factors can relate to each other as the way by which cold air intake systems enhance the horsepower is the same way for improving throttle response.

Throttle response is how fast the vehicle responds to your acceleration order. Whereas horsepower is the overall power the engine produces.

A cold air intake system with a larger air filter and a wider inlet tube passes and filters more air than smaller ones. Thus, more oxygen is burned and more energy is produced. So, the horsepower increases, and the throttle response is enhanced.

Air filter

Now with the most critical part of the air intake system. The air filter is the center of this system where air flows in and then flows out to the engine.

Air filters either come as oiled filters that need oiling every few miles and washable ones that can be removed and washed with water. The oiled air filters collect dust and dirt and stick them to the oil. Thus, after a certain number of miles, they need cleaning and re-oiling. Whereas washable ones filter the air as home air conditions. When the filter becomes accumulated with dust, it needs washing.

If we are to choose between both options, we will choose washable ones as they are more practical and easier to use. However oiled filters can collect more containments.

FAQs for the Best Cold Air Intake for 6.7 Cummins

How cold air intake system works?

As the name suggests, cold air intake systems pass cold air to the engine. The aim of this aftermarket piece is to enhance the quality of the air flowing to the engine. Thus, when cooler and purer air flows inside the engine, the combustion process is enhanced. This way, the engine performs better and provides higher horsepower.

Do cold air intake systems improve gas mileage?

Yes, a high-quality air intake system can improve your Cummins Diesel gas mileage. Cold air intake systems improve the efficiency of fuel consumption. This means the same amount of fuel will be used to produce more energy. Thus, utilizing the gas in the best way.

Alternatively, cold air intakes that only utilize their power to produce an aggressive motor sound will reduce the gas efficiency. More fuel will be used to produce aggressive motor sound without any improvement in the gas mileage.

What are the drawbacks of cold air intake?

Ultimately, cold air intakes don’t have drawbacks. They supposedly improve the horsepower and throttle response. Also, they can improve the gas mileage.

However, some car owners as Dodgeram 2500 or 3500 install the cold air intake to get the aggressive sporty sound only. If this is the case, you still need to get a high-quality cold air intake so as not to downgrade your car’s performance.

Is exhaust the same as air intake kits?

While both systems work to improve the engine performance, their mechanism of work is different. Cold air intakes are mainly for filtering the air flowing to the engine.

On the other side, car exhaust systems take the air product of the combustion process and divert it outside the vehicle.

So, in a nutshell, the two systems have corresponding effects. Yet, they both work to deliver the same result. If you are to choose between both, then, we recommend a cold air intake system as it is cheaper and more effective.
