Best Cold Air Intake For 5.9 Cummins – Buyer’s Guide
When searching for the perfect cold air intake, navigating through the various types and benefits can be daunting. While technically, there is only one “true” standard model, a few variations exist. Understanding which is best for your truck requires a deeper look.
The three primary types of cold air intake are the standard model, the ram intake, and the short ram intake, each offering unique benefits. Although there’s no universal “best” type, certain trends tend to emerge regardless of your make and model.
Ultimately, choosing the right cold air intake boils down to several key factors that must be considered. By weighing your options against these factors, you’ll land on the perfect fit for your vehicle.
Here’s what you should look out for when selecting the best cold air intake for 5.9 Cummins:
-Cold Air Intake
Cold air intakes are the go-to for anyone looking to boost their engine’s performance. Essentially, these intakes take cool air from outside the engine compartment and pump it to your engine. But how do they work exactly?
Firstly, let’s compare them to traditional stock air intakes. The cold air intake differs from the stock version in that the filter is positioned at the front of the inlet. Here, it can filter the air away from the engine and keep its temperature in check. From here, the air follows a pipe or tubing system that feeds directly into the engine.
This is where things get interesting. Because the cold air intake feeds at lower temperatures, the air is denser and has a higher oxygen concentration. In turn, this helps your engine fire better. The benefits of installing a cold air intake go beyond just performance. Many of these systems will position the filter at the very front of the vehicle, as far away from the engine as possible. This way, the air is as cool as can be.
But there’s a risk too. With the filter so exposed, it can be much more susceptible to any nasties that get tossed up on the road. To combat this, some manufacturers include a pre-filter to catch any pesky debris. This ensures the main filter stays in good condition, allowing your cold air intake to work for longer.
So, if you want to breathe new life into your engine or protect your air filter from unwanted contaminants, a cold air intake might be the way to go.
-Ram Intake
The RAM intake system is a popular aftermarket upgrade for engines, but what’s the difference between it and standard cold air intake systems? They’re similar in design, benefits, and issues in many ways. However, one of the main differences lies in the air filter’s position.
The cold air intake kit positions the air filter away from the engine, while the RAM intake system positions it at the back. The tubing arrangement of both systems pulls air from further away from the engine, but the positioning of the filter affects the air temperature. The RAM intake system uses cooler air thanks to its filter placement, whereas the cold air intake heats the air next to the engine.
However, let’s be honest: the temperature of the air doesn’t matter too much. It all depends on your engine and the customizations made to it. Some engines simply run hotter than others, meaning they may not see the full benefits of a RAM intake system.
One thing to note is that a RAM intake system doesn’t provide as cold airflow as a cold air intake system. Plus, they share the same potential issues with inlet openings that can introduce contaminants, including water. Luckily, most RAM intake system manufacturers include pre-filters to mitigate this issue. Not only does this keep out dust and debris, but it also extends the lifespan of your air filter.
-Short Ram Intake
The short ram intake is an essential part of any car enthusiast’s vocabulary as it is one of the three types of air intake. Compared to the ram intake, the short ram intake is similar but with shorter tubing. Although it might not seem significant, the length of the tubing profoundly impacts the intake’s effectiveness.
When swapping from a stock intake to a short ram intake, installation becomes much easier due to its similar positioning. The short ram intake’s compact size makes it suitable for installation in tighter areas, giving you more space to tinker. But while the short ram intake’s proximity to the engine bay provides a shorter path for air to enter the engine, it also has drawbacks.
The air temperature increases with each passing rotation, leaving the air’s oxygen concentration low. As a result, the short ram intake feeds the engine air that’s less cool and dense than cold air intake types. Even so, the short ram intake moderates airflow more than cooling it, making airflow more constant. The short tube allows for more direct airflow than the stock intake, leading to a steadier air flow with fewer twists. The result is a larger air inlet that delivers more total air to the engine.
In addition to providing steadier airflow, short ram intakes are typically less expensive than other aftermarket intake systems. So there you have it. You’ll get what you paid for with a better understanding of the benefits of a short ram intake.
4 Important Cold Air Intake Features
Upgrading your Cummins motor with a cold air intake system can provide many benefits: increased performance, better fuel economy, more power, and even some envy from fellow drivers. But what exactly can you expect from this aftermarket modification? Here are the four main reasons to make the switch.
-An Aggressive Sound
Upgrade to a good CAI system to have your Cummins engine roar like a super beast with a throaty rumble. Elevate your driving experience by adding the Best Cold Air Intake for Aggressive Sound, aFe Power Magnum FORCE 51-11342-1.
-Increased Power
Installing a cold air intake system can boost your Cummins engine’s horsepower by 5-20 units! The factory’s intake system is designed to produce the bare minimum acceleration and horsepower, as cost is the determining factor. However, with the aFe Stage 2 Pro-5R, you can increase power like never before. Get ready for better performance and an all-around, more satisfying ride!
-Fuel Economy
Given the soaring gas prices, fuel mileage has become a paramount concern, particularly when it comes to diesel fuel. Hence, even a modest improvement in MPG can significantly offset costs incurred for installing a cold air intake system. As a result of enhancing your diesel engine’s breathing capacity, you’ll easily upsurge fuel economy. To that end, consider the aFe Stage 2 Pro-5R: it’s the best cold air intake system that optimizes fuel economy for your vehicle.
-Less Maintenance
Cold air intake systems with integrated filters are commonly recommended for efficient engine performance as they prevent harmful particulates that can cause damage. The K&N 57-1532 or 57-1525 are among the best cold air intake systems, requiring fewer and further spaced cleanings or replacements (ideally between 50,000 and 100,000 miles). These filters can serve you longer, save time, and reduce maintenance costs.
5.9 Cummins Cold Air Intake Performance Benefits
The advantages of installing an upgraded intake for the 5.9 Cummins extend beyond increased horsepower and Torque. A cold air intake helps enhance airflow by a whopping 30-50% over the stock intake, drastically benefiting turbo spool time and throttle response. And if that’s not remarkable enough, installing a more advanced intake can even lead to a 1-2mpg boost in gas mileage. You’ll experience increased power, efficiency, and overall engine performance with an intake system upgrade.
Benefits of adding a cold air intake to the 5.9 Cummins include:
- Increased horsepower gains of 5-10whp+
- Increased torque gains of 10-20wtq+
- Airflow increases by 30%-50%, improving overall engine performance
- Better throttle response for improved acceleration
- Faster turbo spooling, enhancing power delivery
- Improved fuel efficiency with potential 1-2mpg increases
- Cool turbo and intake noises add to the overall driving experience.
Improving engine power and performance is crucial to owning a 5.9 Cummins. But what about the impact of a cold air intake system on power gains? Well, the answer is not straightforward.
Power gains from a cold air intake can vary as it depends on what other mods you have. Hence, a completely stock 5.9 Cummins will likely see power gains on the low end of both ranges.
However, a tuned engine will experience power gains more towards the top end of the range as upgraded intakes increase the volume of air to the turbo. This is where the stock intake can become restrictive, and power gains can be better on tuned engines.
That’s not all; upgraded intakes increase horsepower and Torque at low-end power curves. Although we quoted power numbers for peak power gains, the gains are prevalent throughout the power curve, even though a stock 5.9 Cummins might show zero peak power gains.
-5.9 Cummins Cold Air Intakes vs. Other Intakes
Cold air intakes are the go-to name for upgraded intake systems, particularly among 5.9 Cummins enthusiasts. Yet, it’s not entirely accurate regarding upgraded systems for this particular engine. Typically, cold air intakes redirect the intake filter to a colder area within the engine bay, usually found at the lower front bumper area. This clever configuration aims to bring in fresher air and boost engine performance.
But wait, there’s more. Other terms used are ram air systems or performance intake systems, and the list goes on. Notably, virtually every 5.9 Cummins intake system is technically a ram air intake. Rather than focusing mainly on cooler air, ram air intakes aim to decrease restrictions and improve the flow of air, maintaining the stock air filter location.
The type or name of the intake is not as critical as the type of system – open or closed intake. Now you’re up-to-speed on intake systems for 5.9 Cummins engines and ready for informed and confident decision-making.
Open vs. Closed Intakes
When choosing an intake for your 5.9 Cummins, your decision comes down to the type: open or closed. An open intake exposes the air filter to the engine bay, while a closed intake houses the filter in a box. Even “open” intakes use heat shields to protect the air filter from engine heat.
While closed intakes pull in slightly cooler air since they aren’t directly exposed to engine heat, it doesn’t matter much. Turbo engines aren’t affected by intake air temps since the intercooler effectively cools the air before it enters the combustion chamber.
The big difference? Open intakes will increase airflow to your engine by around 20% compared to closed intakes. This translates to better performance and power gains. But bear in mind that open intakes can be noisy, with more turbo and intake induction noises than most closed intakes.
Some people opt for heat shields to shield their air filters from engine heat, but we don’t think they are necessary. While the shield might make your engine feel slightly cooler, it doesn’t make any difference.
If you’re looking for the most bang for your buck, choose an open intake. We love the additional airflow and added power they provide. But, if you prefer a quieter ride, a closed intake might be a better choice.
