Auto Dynasty offers several replacement parts for vehicles. This air intake system is one of them that you can call a good offer. Being compatible with 2007-2008 6.2 Denali, it offers a visible improvement in engine performance.
I have used this several years ago and found a satisfactory change in my engine. It allowed me to perform better towing, gave me better control over acceleration, and blessed my ears with a better engine sound.
Auto Dynasty utilizes high-quality t-6061 aluminum as a core material for the cold air intake unit. It is robust, durable, and at the same time pretty lightweight, leading to high airflow in the combustion chamber.
The red filter of this air intake system is designed and made to take out most of the contaminants from the air and deliver clean air to the engine. It provides 95% filtration efficiency. I found it perfect for the task because it was able to catch micro-contaminants too. You can’t complain about it.
I love the airflow path too. You won’t find much to complain about it too. Further, it improves gas mileage too which is the most desirable thing for the car owner.
However, you might complain a bit about the heat barrier. It comes to save the filter from engine heat and it does the job very well. But you may find a problem while installing and you’ll have to trim it for perfect placement.
Except for this, it doesn’t create any other problem at the time of installation. Overall, it seemed to be a great performing CAI to me.

Buying Guide for the Best Cold Air Intake for 6.2 Denali
When you’re going to select the perfect cold air intake for 6.2 Denali or any other model, focusing on several features is a must. That’s why I’m sharing the points you must check at the time of buying a cold air intake. This will help you to pick a better option.
Compatibility
Cold air intakes are made to be compatible with the makes and models of vehicles. So, you should pick the perfect one that is compatible with the specific make, model, and year of your vehicle. Otherwise, you’ll receive one that won’t sit under the hoods of your vehicle.
Doing such mistakes would bring some unwanted hassle for you. So, before checking anything else, make sure that you’re seeing something that is made compatible with your vehicle.
Type of Filter
You’ll find two basic types of filters- dry filter and oiled filter. Oiled filters come with oil applied to it which helps them to catch small contaminants. On the other hand, dry filters don’t come with something like this.
The advantage of oiled filters is- they come with larger openings. As oil allows them to catch maximum contaminants, large openings are not a problem at all. Because of large openings, they can deliver more air to the engine.
As dry filters don’t come with oil, they have smaller openings. So, they send less air to the engine than the oiled ones. But dry filters are easier to maintain compared to oiled filters.
Now you have to pick one according to your comfort. I suggest choosing oiled filters.
Filter Material
Air filters of CAIs are made of several types of materials. Paper is one of the most used materials used to make air filters. Paper filters are comparatively cheaper in price. But they are not reusable. You’ll find foam filters too. They are very effective in catching contaminants. But airflow is not good in these filters.
Cotton is another common material that is found in CAI systems. They are the most effective from the perspective of airflow and filtration. Also, most of the cotton filters are reusable too.
You’ll find steel air filters too. They are not very efficient from the perspective of catching micro contaminants. But if you think from the view of airflow, they ensure maximum airflow to the engine. They are typically used for racing.
I suggest going for CAIs that come with cotton air filters.
Airflow Pipe Material
Two common materials for airflow pipes are aluminum and plastic.
Plastic airflow paths keep the air safe from the engine heat. But sometimes they are prone to damage caused by the heat. Aluminum pipes can survive from the heat. But it might make the air hot while flowing towards the engine.
Several CAIs use technology that allows plastic pipes to withstand more heat. Similarly, some companies use technologies so that the aluminum pipes barrier the heat properly.
So, pick according to your choice.
Durability
The cold air intake you’re picking should be durable so that it can support you for a long time. Check the manufacturer’s warranty to be sure about the durability of the CAI you’re looking at. Also, you can find and read the user reviews for checking the average durability of a CAI. Don’t spend on something that is not that durable.
Ease of Installation
Typically exact-match CAIs are easy to install. However, there might be issues like not using factory accessories or the need for a minor change, etc. I suggest avoiding these issues. Minor trims can be done, but avoid that too if possible.
Heat Shield
Though many people disagree but the heat shield is another vital part of the CAI, I must say. It is used to save the filter from the heat produced by the engine. Because of the engine heat, there is hot under the hood. The filter can get affected by this heat. This is why a heat shield is used.
Make sure that the CAI comes with a strong heat shield. Some type of coating would be great.
Price
As you’re investing in an expensive upgrade, keeping your eyes on the price is a must. If you find two similar types of CAIs from known brands, I suggest going for the cheaper one. If the price difference is huge, you should be very careful before going for the cheaper one. User reviews would support you for checking this matter.
Is It Worthy Invest in Cold Air Intake?
You’ve heard a lot about how CAI systems increase the engine performance of your car or truck. In this article, I’ve said this point several times. So, being interested in installing a cold air intake is natural.
But if you’re studying about CAIs, you’ll see many people have disagreed with all such opinions about CAIs. So, a question might arise- is it worth investing in cold air intake?
Cold air intakes improve the performance of your vehicles and show some noticeable improvements in acceleration, torque, speed, sound, towing, and a few other cases. But there are many other factors too.
If you install a cold air intake in a new vehicle, you won’t find a huge improvement in the engine performance. But if you get it installed after running several thousand miles, you can expect a noticeable performance improvement.
Also, only investing in a cold air intake system might not give you a pleasant performance improvement. You should make some other upgrades too.
Depending on the vehicle itself, the result of installing a cold air intake varies. Some engines are really good when they get cold and fresh air at a huge amount.
So, if you’re looking for a huge improvement in the performance of your engine, installing a cold air intake only might not satisfy you. Still, I think it is worth it because the slight improvement it provides is constant for a long time.

Frequently Asked Questions About CAI System
How cold air intake improves engine performance?
Your engine works by burning gas with the help of air. More air means more efficient burning of fuel. When fuel is burnt more efficiently, the engine gets more power to run. This allows the engine to perform better.
Cold air intake delivers more air to the engine compared to regular air filters. Also, these are efficient in filtering air and removing as many impurities as possible. This also allows the air to burn the fuel better.
Does CAI damage the engine?
CAI doesn’t damage the engine. However, some issues like the MAP sensor failing during installation may happen because of human error. CAI doesn’t have anything to do with this issue. To avoid such issues, you have to be careful at the time of installing it.
Also, some issues may happen because of over-oiling the filter. Again, this is not the responsibility of the cold air intake system. You should stay careful while oiling it.
Are dry filters cleanable and reusable?
You won’t find many dry filters that are washable and reusable. Searching desperately might bring one or two, depending on your vehicle model. But there is a huge scope that you won’t find any such filter.
Typically, oiled filters are washable and reusable.
