Best Cold Air Intake for Diesel Trucks

There are many cold air intake systems on the market, but which one is the best for diesel trucks? We’ve put together a list of the best cold air intakes for diesel trucks, based on our findings. These intakes will help your truck run more efficiently and make more power.

If you’re looking for the best cold air intake for diesel trucks, there are a few things you need to keep in mind. First off, diesel trucks tend to be much larger and heavier than their gas counterparts, so you’ll need an intake that can handle the increased airflow. Secondly, diesel engines produce a lot of heat, so you’ll want an intake that can help keep your engine cool.

And finally, because diesels are typically used for towing and hauling, you’ll want an intake that won’t restrict airflow and will help your engine breathe easier. There are a few different companies that make cold air intakes specifically for diesel trucks, so do some research and see which one is right for your truck. You might also want to consider upgrading your exhaust system at the same time, as this will further improve airflow and help keep your engine cooler.

With the right cold air intake installed, you’ll notice improved performance from your diesel truck – it’ll run smoother and more efficiently while also sounding great.

Diesel Cold Air Intake Pros And Cons

Diesel engines are known for their power and efficiency. A diesel cold air intake can improve both of these characteristics. However, there are also some potential drawbacks to consider before installing one on your vehicle.

The biggest benefit of a diesel cold air intake is the increased airflow it provides. This can lead to better engine performance and fuel economy. The increased airflow can also help to prevent overheating by keeping the engine cooler.

Another advantage of a diesel cold air intake is that it can provide cleaner air for the engine to burn. This can result in less wear and tear on the engine over time, as well as improved emissions. However, there are some potential downsides to consider as well.

One is that a diesel cold air intake can sometimes cause false knock sensor readings. This means that your engine may think it is knocking when it really isn’t, which could lead to premature ignition timing and decreased performance. Additionally, a cold air intake can sometimes cause water condensation inside the filter, which could lead to rust or other damage if not properly maintained.

Do Cold Air Intakes Help Diesel Trucks?

A cold air intake is an aftermarket engine modification that replaces a vehicle’s stock air intake system. A cold air intake typically draws in cooler air from outside the engine bay, which can result in increased power and improved fuel efficiency. Many people believe that cold air intakes are especially beneficial for diesel trucks, as the cooler air can help to increase combustion and improve engine performance.

However, it’s important to note that there is no definitive proof that cold air intakes provide any significant benefits for diesel trucks. In fact, some experts believe that cold air intakes can actually be detrimental to a diesel engine’s performance, as they can allow water and other contaminants to enter the engine.

How Much Horsepower Does a Cold Air Intake Add to a 6.7 Cummins?

Adding a cold air intake to your 6.7 Cummins can increase horsepower by up to 15%. The increased airflow that a cold air intake provides can make a big difference in engine performance, particularly when towing or hauling heavy loads.

Does a Cold Air Intake Change the Sound of a Diesel?

If you’re a diesel enthusiast, you know that the characteristic sound of a diesel engine is one of its defining features. So it’s no surprise that many diesel owners want to enhance that signature sound with a cold air intake (CAI). But does a CAI actually change the sound of a diesel engine?

In short, yes, a CAI can change the sound of your diesel engine – but not in the way you might think. A CAI doesn’t actually make your engine louder, per se. Rather, it changes the tone of the exhaust note by making it deeper and more aggressive.

Think of it as giving your diesel engine a “throatier” sound. Of course, there are other benefits to installing a CAI on your diesel engine beyond just changing the sound. A CAI can also help improve airflow and thus increase power and efficiency.

But if you’re just looking to change the sound of your engine, then a CAI is definitely worth considering.

Are K&N Filters Good for Diesels?

There are a lot of opinions out there about K&N filters, with some people swearing by them and others saying they’re not worth the money. So, are K&N filters good for diesels? The short answer is that yes, K&N filters can be good for diesel engines.

They can help to improve airflow and increase power. However, they may also cause issues such as increased fuel consumption and shortened engine life. Ultimately, it’s up to you to decide whether the benefits of a K&N filter outweigh the potential downsides.

If you’re considering using a K&N filter on your diesel engine, make sure to do your research and weigh all the pros and cons before making a decision.


Diesel trucks are built for towing and hauling, which means they need lots of power. And one way to get more power from your diesel truck is to install a cold air intake. A cold air intake will help your truck’s engine by bringing in cooler, denser air.

This means that the engine can burn fuel more efficiently and produce more power. There are many different cold air intakes on the market, so it’s important to choose one that’s specifically designed for diesel trucks. We’ve put together a list of the best cold air intakes for diesel trucks, so you can find the right one for your needs.
