If you're running a 6.7 Cummins, you know airflow is everything. A cold air intake (CAI) is one of the simplest and most effective upgrades you can make to boost performance, throttle response, and engine efficiency. The factory intake does its job—but it’s restrictive. More airflow means cooler intake temps, better combustion, and more efficient power delivery. That’s why upgrading to a high-performance cold air intake is a no-brainer to lower EGTs, improve MPG, and wake up your turbo.

But with so many brands and options, how do you pick the best cold air intake for 6.7 Cummins performance? We’re breaking down top-rated brands like S&B, Banks, and AFE to help you find the right setup for your build. Whether you want maximum airflow, a deeper turbo whistle, or the most durable design, we’ve got you covered. If you’re ready to shop, explore Cummins cold air intakes to see what’s in stock. Otherwise, let’s break down what you need to know.

Choosing the Best Cold Air Intake for 6.7 Cummins Performance: What to Look For

Before throwing parts at your truck, it pays to understand what makes a good cold air intake. Not all CAIs are built the same, and picking the wrong one can mean gains you’ll never feel or filters that clog up faster than they should. Here’s what separates the best from the rest:

• Open vs. Closed Air Boxes: Open air filters give you maximum airflow and turbo sound, but they’re exposed to heat from the engine bay. Closed airboxes provide better heat insulation, keeping intake temps lower for more consistent performance. (If you want more details on this, check out our deep dive: Open vs. Closed Cold Air Intake: Which is Better?)
• Filter Type: Oiled cotton gauze filters offer reusable, high-flow performance, while dry synthetic filters are low-maintenance and better for dusty environments.
• Build Quality & Fitment: Cheap plastics and weak clamps won’t hold up. You want OEM-like fitment with high-quality couplers, durable seals, and solid hardware.
• Performance Gains: Not all intakes make the same power. A well-designed system increases CFM (cubic feet per minute) for better combustion and faster turbo spool, while poorly designed intakes might not flow much better than stock.

Best Cold Air Intakes for 6.7 Cummins (Brand Comparisons)

When choosing between the best cold air intakes for the 6.7 Cummins, different brands stand out for different reasons. Some prioritize maximum airflow, others focus on fuel efficiency, and some deliver an aggressive turbo sound. At Diesel Power Products, we only carry brands we trust, tested by real diesel enthusiasts who know what works. Below, we break down the top three cold air intakes for the 6.7 Cummins, based on performance, durability, and real-world customer feedback.

S&B Cold Air Intake for 6.7 Cummins – Best for Maximum Airflow

If you want top-tier airflow without sacrificing filtration, S&B is the brand to beat. Their cold air intakes are dyno-tested, high-flow, and built with a fully enclosed airbox to prevent heat soak from under the hood. The precision-fit design ensures a tight seal, while the oversized filter allows for maximum cold air intake without restriction. Unlike cheap, open-style filters that suck in hot engine bay air, S&B keeps intake temps down for better throttle response and lower EGTs, making it an ideal choice for towing and high-load applications.

Real-world results back it up. One Cummins owner who installed an S&B on his 2015 Ram 2500 6.7L Cummins said:

“Absolutely awesome… first of all shipping was super super fast! Amazing! Second of all the intake was very simple to install and gave me a little more volume from the turbo but REALLY INCREASED AIR FLOW AND LOWERED EGT. Stared at my programmer for about 3 miles hammer down and noticed significantly more airflow and lower intake temps as well as lower EGT. Great product represented by an awesome company.”

Another driver who upgraded his 2014 Ram 2500 was just as impressed:

“TOTALLY IMPRESSED! Installed on my cab in less than an hour. Very clear installation instructions! The turbo is noticeably louder inside and out (with some throttle). The exhaust brake has a deeper tone and more growl. Honestly, sounds more like a BIG RIG!! I should've bought it long ago… makes me smile!”

For a high-performance intake with superior fitment and filtration, S&B is the go-to choice for daily-driven and tuned Cummins trucks. Learn more about S&B Cold Air Intakes at Diesel Power Products or check out a "> detailed S&B Cold Air Intake review on YouTube to see how it performs.

Benefits of a 6.7 Cummins Cold Air Intake Upgrade

Upgrading to a high-performance cold air intake is one of the easiest and most effective ways to unlock more power, improve efficiency, and enhance throttle response on your 6.7 Cummins. The stock air intake is built to meet emissions and noise regulations, not necessarily for maximum performance. By switching to a better-designed intake system, you eliminate airflow restrictions, giving your turbo more of the cool, dense air it needs to perform efficiently.

Increased Airflow & Turbo Spool

The 6.7 Cummins relies heavily on airflow—more oxygen means better combustion, quicker turbo spool, and improved throttle response. Stock intakes, particularly on newer models, restrict airflow with smaller inlets, sound baffles, and inefficient filtration materials. Aftermarket intakes, like those from S&B, AFE, and Banks, use larger-diameter tubing and high-flow filters to increase airflow while maintaining proper filtration.

Lower Exhaust Gas Temperatures (EGTs)

Heat is the enemy of any turbocharged diesel engine. Lowering EGTs (exhaust gas temperatures) extends turbo life, improves reliability, and helps maintain efficiency under load. By reducing intake restrictions, a cold air intake allows cooler, denser air into the turbo, preventing excessive heat buildup—especially beneficial for those towing heavy loads or running performance tunes.

Improved Fuel Economy

Some drivers report small but noticeable MPG gains after upgrading to a higher-flowing cold air intake. While fuel economy improvements vary, reducing restriction and improving combustion efficiency can lead to minor MPG increases under normal driving conditions. Gains are often more noticeable when paired with other upgrades like an efficient exhaust system or performance tuning.

Stronger Turbo Sound & Throttle Response

A cold air intake isn’t just about numbers—it enhances the driving experience. Many Cummins owners love the more pronounced turbo whistle and deeper intake growl that comes with a high-flow intake system. Under acceleration, you’ll notice sharper throttle response, especially at low RPMs when turbo lag is more apparent.

The Verdict: Is a 6.7 Cummins Cold Air Intake Worth It?

For 6.7 Cummins owners, a cold air intake is one of the most cost-effective upgrades you can make. It’s a simple bolt-on mod that improves airflow, turbo spool, and throttle response, while also helping to lower EGTs—critical for those who tow, haul, or push their trucks hard.

While you won’t see massive horsepower gains from an intake alone, the real benefit is in reducing restriction and optimizing airflow, which leads to smoother acceleration and better combustion efficiency. Some drivers also report small but noticeable MPG improvements, especially when paired with other airflow and tuning upgrades.

A well-built intake from brands like S&B, AFE, or Banks will also outlast stock components, with reusable high-flow filters that save money in the long run. Whether you want maximum airflow, aggressive turbo sound, or a reliable factory-style upgrade, a cold air intake delivers solid, real-world performance improvements.
