Cold Air Intakes & High Flow Air Filters for Diesel Trucks

If you’re looking to get more out of your diesel truck or car, upgrading your air intake system is one of the smartest moves you can make. Cold air intakes and high flow air filters are popular upgrades for drivers who want better performance, more efficient engines, and even a more exciting driving experience. These parts are not just for hardcore enthusiasts—anyone who wants a stronger, more responsive vehicle can benefit from a better intake system.

The air intake system is basically your engine’s way of “breathing.” The more air your engine gets, the more fuel it can burn, and the more power it can make. Factory air intake systems are usually designed to be quiet and inexpensive, but they can be restrictive. This means your engine isn’t getting as much air as it could, especially when you’re asking for more power—like when towing, passing on the highway, or climbing hills.

A cold air intake replaces the factory airbox and intake tube with a larger, smoother system that pulls in cooler, denser air from outside the engine bay. Cooler air contains more oxygen, which helps your engine burn fuel more completely. This can lead to noticeable gains in horsepower and torque, especially on turbocharged diesel engines. You’ll also get a sharper throttle response and, in many cases, a slightly deeper engine sound that many drivers find more satisfying.

S&B Filters: A Trusted Name in Performance

When it comes to cold air intakes and high flow air filters for diesel trucks, S&B Filters is a brand that stands out. S&B has built its reputation on quality, innovation, and real-world results. Their cold air intakes are specifically engineered for popular diesel trucks, including Ford Powerstroke, Dodge Ram Cummins, and Chevy/GMC Duramax models.

S&B’s high flow filters are made from premium cotton gauze or synthetic materials, designed to let in more air while still trapping dirt and dust. Many of their filters are reusable and can be cleaned and re-oiled, saving you money over time compared to disposable filters. The intake kits are designed for a direct fit, so installation is straightforward—even if you’re not a professional mechanic.

One of S&B’s unique features is the clear lid on many of their intake boxes, which lets you easily check your filter’s condition without taking everything apart. Their intake tubes are also designed to minimize bends and restrictions, creating the smoothest possible path for air to reach your engine.

High Flow Air Filters: Simple but Effective

If you’re not ready to swap out your whole intake system, a high flow air filter is a great place to start. High flow filters are designed to fit in your factory airbox but allow more air to pass through than standard paper filters. Brands like S&B, K&N, and AFE make high flow filters for most diesel trucks and cars.

The main advantage of a high flow air filter is that it’s an easy, affordable upgrade with real benefits. You might not get as much power as a full cold air intake, but you’ll still see better throttle response and possibly a small bump in fuel economy. Plus, most high flow filters are washable and reusable, so you don’t have to keep buying new ones.

Diesel Intake Upgrades: What to Expect

So, what can you expect after installing a cold air intake or high flow filter? Most drivers notice their engine feels more responsive, especially when accelerating from a stop or merging onto the highway. Turbo diesel engines, in particular, benefit from the increased airflow, as they rely on a steady supply of cool air to make boost.

You might also hear a deeper, throatier engine sound when you get on the throttle. For many diesel owners, this is a welcome bonus—it’s a sign your engine is breathing better and working more efficiently.

Some drivers also report a small increase in fuel economy, especially during highway driving or towing. While the gains aren’t always dramatic, every bit helps when you’re trying to get the most out of your fuel tank.

Installation and Maintenance: Easier Than You Think

One of the best things about upgrading your air intake or filter is how straightforward the process is. Most cold air intake kits come with detailed instructions and use basic hand tools. In many cases, you can complete the installation in under an hour. If you can change your own oil, you can probably handle this upgrade.

Maintenance is also simple. High flow filters should be cleaned and re-oiled (if applicable) every 10,000 to 20,000 miles, or more often if you drive in dusty conditions. S&B and other brands offer filter cleaning kits that make the process easy. Keeping your filter clean is important for maintaining performance and protecting your engine.

Are There Any Downsides?

While cold air intakes and high flow filters are great upgrades, it’s important to choose quality parts from trusted brands. Cheap filters may let in more dirt, which can damage your engine over time. Also, some intake systems may increase engine noise, which some drivers love but others might not.

If you live in an area with strict emissions rules, check that your chosen intake system is street legal. Many S&B intakes are CARB certified, meaning they meet emissions standards in places like California.
