Arriving in the first place is the 75-5092 Cold Air Intake by S&B Filters. It is the product to buy if you have a Dodge Ram from 2010 to 2012.

It is a pretty fantastic product, and with over 100 ratings, it is popular among users.

So, let’s see what makes it so good!

Before going into the details, this filter is legal in all states of the USA. So, if you were worried about that, you won’t have to be.

This cold air intake is claimed to have approximately 52% more airflow. This is when comparing without it.

The difference is quite huge, which will certainly impact the performance of your engine. The brand claims that its product has a 99.50% efficiency rating.

In layman’s terms, there is no loss of any kind from this product. And if you are worried, this intake has been tested using the ISO 5011 standard.

The intake has been tested to ensure you won’t get any error codes or check error lights. But, unfortunately, this is a common problem with several intakes on the market.

Well, you won’t have to worry about that anymore. The intake has an 8-ply cotton filter. If you don’t know the importance of that, this filter traps all dust particulates.

This ensures that the engine is not contaminated with anything. The filter has also been oiled using robots to ensure the perfect amount is applied.

Moreover, the exact amount of oil used is 90 grams. Although this filter is cleanable, the brand does offer replacement filters.

This means that you won’t have to worry if the filter gets worn out. This makes the buy more appealing for buyers.

All buyers were happy with this product. They had no complaints and issues. One buyer, on the other hand, received a product that was very poorly made.

For example, the holes on the lid had to be drilled to be used. He also noticed decreased mpg. This must have happened due to a faulty unit, most probably.

  • Replacement filters available
  • 52% more airflow
  • Almost 100% efficient
  • No error codes or check lights
  • May send the defective unit

Out of 140 people, only one had an issue. So, the chance of such a thing happening to you is close to zero.

S&B Filters has made a fantastic product, and if you choose to order it, you will love it.

2. S&B Filters 75-5068 Cold Air Intake

Wow! Taking the second spot on this article is yet another product by S&B Filters.

This tells you about the quality of their products and how much consumers prefer them over other brands.

This air intake has been designed for the 2013 to 2018 models of the Dodge Ram with the 6.7 Cummins.

So if you loved the previous product but had a newer truck model, then this product is the one for you.

If you have performance issues as stock settings, then this intake will solve all your issues.

In addition, thanks to the 54.60% better airflow possible with this product, your engine won’t ever have to face air restriction ever again.

The common problem with air intake filters is that they get dirty quite quickly. That is to be expected as they are exposed to the air all the time.

That is why the manufacturer has included a fully enclosed airbox that keeps the filter clean and protects it from the engine’s heat. Engine temperatures get quite high.

This airbox prevents all that heat from reaching the intake to ensure it will not fail before time. Talking about the air filter, the one in this intake is made up of 8-layered cotton.

It is highly effective in blocking all dust particles. So you can rest assured that the air reaching your engine will be as clean as possible.

Lastly, the best thing about this product is that it has two inlets. This means that you can have two airflow paths, unlike one in the stock airbox.

Dual inlet airflow means excellent combustion and a better engine temperature than ever before.

With this product, the buyers had two main issues.

First, they stated that the brand sent out the wrong products, and they declined to exchange them for the correct ones.

This is unacceptable because it is not even the buyer’s fault.

  • More than 50% improvement in airflow
  • 8-layered cotton for dust trapping
  • Dual inlets for massive airflow
  • Fully enclosed airbox
  • The manufacturer may send the wrong product
  • Does not accept returns

Although more than 95% of the buyers were satisfied with their purchase, S&B Filters broke the customers’ trust by not sending them the correct item.

It is a bit of a risk to order this one from them, but you will surely be more than content if the product is the correct one.

Whoa, that name is a mouthful. Taking the third spot on this list is the Magnum FORCE 51 Performance Intake System by aFe Power, a brand that I have written on before.

These guys make everything many aftermarket parts for vehicles. From exhaust systems to electronics, they are experts at what they do.

I have written upon several of their coil-overs, and the brand knows what it is doing.

This system has been designed for Ram trucks which were manufactured during the years 2003 and 2009.

I know it is hard to believe anyone based on what they are saying. However, some statistics show that this intake system is one of the excellent on the market.

When compared to the factory intake, this one outflows it by 105%. That is more than double the flow you were getting before.

The difference is that after using this intake, you will get an additional 14 Horsepower in your engine.

Now, that is incredible. The 3-layer filter used in this one is non-oiled and easily washable.

In addition, it is synthetic, meaning it is not only easily washable but provides you with the ultimate balance between protection and performance.

This is something that cannot be said for some other intakes. Even the heat shield has one piece, meaning it does not require any assembly at all.

This makes the system extremely convenient to use too. It’s like aFe has listened to the consumers and introduced features that all will love.

And, finally, the cherry on top is that this intake is legal in all 50 states of the USA. This means that you won’t have any issues due to the gained horsepower or torque in the states.

Buyers reported that this intake system is not the right size for some Ram models. For example, a 2009 Ram owner complained that the filter was too big for the housing box.

Another owner of the 2007 Ram stated that the intake tube was too short to attach to the filter.

This means that either the system is incompatible, making this product wrongly advertised, or those two buyers received faulty units.

  • 105% better airflow
  • 14 Horsepower gain
  • One-piece heat shield for convenience
  • Legal in all of USA
  • May receive incompatible product

Although aFe has created a stunning product, they really must look into these issues.

In addition, they should improve their quality control, so fewer faulty products leave the assembly line.

Believe me when I say that the competition on this list is extremely high. It isn’t easy to place products, one over the other, because they perform so similarly.

So, arriving in a very close fourth place is the High-Performance Intake by K&N. This product has some pretty fantastic offerings which you will surely love.

This intake system has been dyno tested to ensure its performance. It has been proven that it will provide you with 50% more airflow than the stock airbox, which is restrictive.

The brand guarantees an improvement in horsepower and performance with this product.

If you can use your truck for heavy-duty purposes such as towing or hauling, this system is perfect for you. It also improves the throttle response of the engine.

Do you want your 6.7L engine to roar more?

Well, thanks to the better combustion possible due to this intake, you will hear the sound the engine was designed to produce.

In addition, you and the other people around you will feel and hear the power present under the hood.

Perhaps the most attractive feature of this intake system is that the brand offers a 10-year of one-million-mile warranty.

This is an excellent offering that makes sure that any faults and issues will make you eligible for a free-of-cost replacement.

Furthermore, the warranty is so long that you can consider it a lifetime one. So you won’t have to worry if the product turns out to be defective or any fault shows up during its usage.

Although most buyers had a pleasant experience with this product some were nothing short of dissatisfied with its performance.

Some had fitment issues, while others complained about poor fuel economy after installing this product.

The most probable reason is that those buyers must have received faulty units.

  • Million-mile/10-year warranty
  • Better sound
  • 50% more airflow than stock settings
  • Faulty units sent

If K&N did not have poor quality control, then the product would have scored a much higher place on this list. Nevertheless, the warranty makes it a tension-free buy for all of you.

5. Sinister Diesel Cold Air Intake

If you have a Ram truck from 2007 to 2012, you must be thinking that a sufficiently good product still has not made its way onto this list.

Well, I have got you covered. This Sinister Diesel Cold Air Intake is another excellent product. Although it earned the last spot on this article, it is not the least.

Readers must understand that these products were chosen from hundreds of different options. So, all of them are far better than the competition.

This intake has been designed for 2007 Ram trucks which were released late in the year. According to the brand, factory intakes are incomparable with its product.

I second that because this intake provides excellent airflow, which will improve the sound and significantly boost the throttle response.

This is a great thing for people who use their trucks for towing and hauling. This air filter also allows users to have a better fuel economy.

Thanks to the mandrel-bent aluminum tubing, this is possible, which allows for a smooth airflow without any friction.

Combine that with the cotton filter media; you get excellent airflow.

The tuning has also been coated with their brand’s signature blue color, which looks great and protects the product from rusting and corrosion.

The installation has also been made easy thanks to the experience and hard work of the engineers at Sinister Diesel.

The drop-in installation procedure needs no prior experience or even complex tools. You probably already have the required tools in the garage.

Overall, the brand has created a product that consumers will certainly love, no matter their use scenario.

Lastly, the product has fewer ratings, considerably less than some other offerings on this list.

This makes the buy a bit of a risk because unless someone uses it in everyday scenarios, there is no way to verify the brand’s claims.

  • Excellent airflow
  • Improved mpg
  • Signature blue coating for corrosion protection
  • Fewer ratings

If you decide to buy this intake, I will request that you leave an assessment online so future buyers know what they are getting into.

Frequently Asked Questions

I saw some critical questions being asked by Ram 2500 and 3500 owners. That is why I have compiled this short and brief FAQs to answer some of these questions.

I hope you find the answers to your questions using this guide. Plus, even if you have the knowledge and don’t feel like reading it, it doesn’t hurt to take a look.

There may be something that may clear up your confusion.

Q1. How Much HP Does A cold Air Intake Add To A 6.7 Cummins?

The answer to this question is around 14 HP. This is perhaps the improvement all Ram owners are looking for when searching for a new intake for their vehicle.

The torque amount is also improved, with it being positive of around 24 pound-feet. This is a substantial improvement which is welcomed by all.

The improvement in both of these values is roughly the same for all intakes. The value may be less, but it won’t be more than that.

Q2. Do I Have To Tune My 6.7 Cummins Engine After Installing An Intake?

No, it is not needed. A cold air intake only directs air towards the engine, which normally does not require any tuning.

However, on the other hand, if you find error codes or check lights, then either the engine must be reset or returned to make those issues go away.

But this is an extremely rare scenario that has a close to zero chance of occurring to you.

Q3. Can I Drive The Truck In The Rain With A Cold Air Intake?

In most normal scenarios, it won’t pose any problems. The truck’s hood does a more than sufficient job of keeping all water out and keeping the engine dry.

But, for example. The vehicle is submerged in water during a flood; then chances are the intake will be damaged. The engine will be damaged in that case too.

But, again, chances of that happening are infinitesimally small.


What are the most reliable intakes for 6.7L Cummins? Let's find out

There you have it, guys, my take on the best cold air intake for 6.7 Cummins.

An aftermarket cold air intake is extremely important if you are one to overwork your truck.

The engine needs to cool down so it does not break down and cause more issues for you. This does not mean that the stock intake is bad.

It’s just that these aftermarket ones outperform them in every single manner. You must be asking which one of these intakes I will recommend.

Well, the answer is easy. I would choose the S&B 75-5092 Cold Air Intake, which also earned the top spot on this article.

If it is not compatible with your truck, the second one, which is also from the same brand, will surely be.
