Cold air intakes are one of the most well-known modifications and enhancements in the automotive community. Renowned for their ability to increase power and torque, create the unique intake sound, and even sometimes improve fuel efficiency! There are many kinds of intakes along with brands. We will explore all the kinds, build types, and brands of cold air intakes to ensure you have the appropriate information to decide on the intake you should buy.
Kinds of Aftermarket Intakes
Cold Air Intake (CAI)
Cold air intake systems, also known as CAIs, are the most common, allowing you to draw cooler and denser (more oxygen-rich) air into your engine. The more oxygen present the better an engine will perform, both power and fuel efficiency will see an increase. Cold air intakes can do this because their air filters sit farther away from the engine than other intakes.
Cold air intake systems also commonly have a heat shield around the filter to keep the airflow as cool as possible by further dividing it from the heat of the engine. Often you’ll spot cold air intakes behind grilles and bumpers in the engine compartment.
Ram-Air Intake
Ram-air intakes share a common factor with cold air intake systems—both devices can deliver cooler air to your internal combustion engine. However, ram-air intake filters sit at the front of the car, near the engine. Sometimes Ram air intakes have heat shields to help block the heat of your engine from the filter and direct air. Ram-air intake systems send oxygen-rich cool air to the engine by sucking it in as the car travels forward. Such a setup can pack a powerful punch on the road and have a positive effect on engine efficiency but usually only when a vehicle is in motion.
Short Ram Intake
If you’re looking for a power gain that won’t take up as much room as other systems, consider a short ram intake. Due to its smaller size, this intake system supplies air to the engine faster than the options above. That said, the air comes from the engine bay, meaning that short ram systems won’t provide the cool air flow that the other options on this list do. Short ram intakes aren’t useless, though. In fact, they’re perfect for anyone looking for a better throttle response.
As you can see, learning the different types of air intake systems is very simple. Now, hopefully, finding the best automotive intake system for your ride will be simple too.
Kinds of CAI Filters
There are two main kinds of Cold Air Intake (CAI) filter types:
Foam Filters
These are a common filter found on cold air intakes for import vehicles although they are starting to lose popularity being outperformed in many aspects by cotton/synthetic intake filters.
Cotton/Synthetic
The most common filter for most modern cold air intake systems. Created using layers of cotton or synthetic fabrics to trap dirt/debris and allow for more efficient airflow than factory.
Oiled
Many of the cotton/synthetic filters will require a layer of intake oil to further trap dirt and dust.
Dry-Flow
Sometimes a cold air intake system will be created to use dry, which means the filter requires no oiling. Generally, most stock intake filters are also dry filters created with paper or foam but are often not as efficient as an aftermarket dry flow filter.
A Dry-flow filter has a better filtering membrane, slightly outperforming oiled filters but only minimally. Because of their ease of use and great performance dry flow intake filters are beginning to become the staple for many auto manufacturers and enthusiasts.
What makes a good cold air intake?
There are lots of good Intakes out there, but a few things help make a great system stand out.
Pipe
The piping in Cold Air Intakes should be smooth, and durable and help to minimize bends the best it can. A good intake pipe is the cornerstone to a great Cold Air Intake as it helps move the air from the outside into your engine in the most efficient manner possible. Intake pipes are often made out of plastic and aluminum which tend to be smoothly bored and have wider diameters than factory allowing for more air to transfer into your engine.
Heatshield
Another important aspect that sets apart an incredible intake from a bad one is whether it has a proper heat shield or not. This helps divide the hot air from your engine and the cooler outside air where your filter will be drawing from. Just because a CAI does not have a heat shield does not mean it’s bad this is because some intakes are routed down into your fender or bumper where other things such as the engine bay or headlights act as a heat shield, however not all intakes are created like this and more commonly will be placed within the engine where a heat shield is required to work its best.
Closed Box
Heatshields come in two main types. Closed boxes and open boxes. Closed feature a closed-off top and bottom only open facing the direction cold air is most likely to be entering to help aid in the draw of cooler air.
Open Box
Open boxes or simply just heat shields are nothing more than a block off from the engine and the filter to help confine your filter to colder air but are less efficient than closed boxes.
Filters
Using a high-quality intake filter is another critical aspect of a good CAI system. Things like filter media, filter frame, and the seal/coupler it uses along with the ability to filter debris and how well it flows air are good things to keep in mind.
Hardware and Couplers
Along with all the performance aspects parts like mounts, couplings, and hardware are also important to consider in your intake system. If your intake moves too much or vibrates apart it loses the ability to filter dirt or draw cool air. Many times sensors are placed within your CAI system and can be impacted by a cheap system further impacting performance.
Why you might want one!
There are a plethora of reasons a cold air intake would be a great modification for you. First and most commonly cold air intakes help to create more power for your vehicle by reducing restrictions and keeping your intake air temperatures down meaning cooler/denser air and more oxygen. It is common to see anywhere from 2-30 hp horsepower gains depending on the kit you buy and the factory restrictiveness of your intake.
Cold air intakes because of their efficiency can sometimes also improve your fuel efficiency.
A cold air intake system (unless you choose to build your own) is relatively easy to install. You will be required to remove your factory airbox, filter, and piping then install your new kit and attach any removed sensors and vacuum lines.
