Cold air intakes deliver measurable horsepower and torque gains while improving throttle response on your diesel truck. We stock S&B and quality alternatives for Ram Cummins, Ford Powerstroke, and Duramax engines. Find your year and engine size below to upgrade your truck's breathing.

Cold Air Intake Systems for Diesel Trucks

A cold air intake replaces your restrictive factory air box with a direct-flow design that pulls cooler, denser air from outside the engine bay. The result: better combustion, faster spool-up, and noticeable power gains—especially when towing. Most intakes add 10-20 horsepower and improve fuel economy under light throttle.

Ram Cummins 6.7L Cold Air Intakes (2007-2024)

Whether you're running a 2007-2012 first-gen 6.7L, a 2013-2018 mid-gen, or the latest 2019-2024 model, we have S&B intakes engineered for your specific year range. Cummins owners see the biggest throttle response improvement thanks to the turbo's demand for unrestricted airflow. The intake also keeps EGR (exhaust gas recirculation) temps lower by supplying cooler charge air.

Ford 6.7L Powerstroke Intakes (2011-2026)

Ford's 6.7L Powerstroke responds aggressively to cold air upgrades. We carry intakes for the 2011-2016 original generation, the 2017-2019 refresh, and the current 2020-2026 platform. Each generation has unique fitment requirements—that's why year-specific selection matters. A quality intake pairs well with a diesel exhaust system to unlock full potential.

GM Duramax Cold Air Intakes (2011-2023)

Duramax owners get solid gains from cold air intakes whether you're running the 2011-2016 LML 6.6L or the newer 2017-2023 L5P 6.6L. Both engines benefit from the cooler intake charge, especially under sustained load. S&B intakes feature sealed designs that prevent hot engine bay air from entering the system.

Why Choose a Cold Air Intake?

  • Power: 10-20 hp and 20-40 lb-ft torque gains depending on your engine
  • Throttle Response: Noticeable improvement in spool-up and acceleration
  • Cooler Charge Air: Denser air means better combustion efficiency
  • Easy Install: Most intakes bolt on in under an hour with basic tools
  • Reusable Filter: Clean and reuse your filter—no ongoing costs

Do cold air intakes work on diesel trucks?

Yes. Diesel engines are air-hungry, especially under boost. A cold air intake reduces restriction in the intake tract, allowing the turbo to spool faster and pull cooler, denser air into the cylinders. You'll feel the difference in throttle response within minutes of installation.

How much horsepower does a cold air intake add?

Most quality intakes add 10-20 horsepower and 20-40 lb-ft of torque, depending on your engine platform and supporting modifications. Cummins and Powerstroke engines tend to show bigger gains than stock Duramax platforms. Actual results vary based on tune, exhaust, and driving conditions.

Is the S&B intake the best option for my truck?

S&B is the industry standard for diesel cold air intakes—they flow tested their designs and engineered sealed systems that pull from outside the engine bay. We also stock quality alternatives at different price points. Year-specific fitment is more important than brand—make sure you select the correct generation for your truck.

Can I install a cold air intake myself?

Absolutely. Most intakes bolt onto existing engine mounts and hoses using basic hand tools. The entire job takes 30 minutes to an hour. No special equipment or tuning required—the intake works immediately on stock trucks, though pairing it with a tune or exhaust unlock more gains.

Will a cold air intake affect my EGR or DPF?

No. A cold air intake only affects the fresh air entering the engine—it doesn't touch your emissions systems (DPF, EGR, or SCR). In fact, cooler charge air can help reduce EGR temperatures and improve combustion efficiency, which is a benefit.

What's the difference between 2013-2018 and 2019-2024 Cummins intakes?

Engine bay layout and intake manifold design changed between generations. Using the wrong year-range intake will result in fitment issues or poor performance. Always verify your truck's production year matches the intake's year range before ordering.

Do I need to rejet or tune my diesel after installing an intake?

Your truck will run fine on a stock tune with just an intake. However, a custom tune optimized for the intake's improved airflow will unlock additional horsepower and responsiveness. Tuning is optional but recommended if you want maximum performance.
