Hey guys! Are you looking to juice up your 2020 Ford Explorer ST? One of the best ways to get some extra horsepower and improve your engine's performance is by installing a cold air intake (CAI). In this article, we're diving deep into everything you need to know about CAIs for your Explorer ST, from what they are and how they work, to the benefits you can expect, and even some recommendations to get you started. So, buckle up and let's get started!

What is a Cold Air Intake?

So, what exactly is a cold air intake, and why should you care? Basically, a cold air intake is a system designed to replace your car's factory air intake system. The main goal of a CAI is to draw in cooler, denser air into your engine. Why is this important? Well, cooler air has more oxygen molecules packed into it than warmer air. When your engine burns fuel, it needs oxygen. The more oxygen available, the more efficiently your engine can burn fuel, resulting in more power. Think of it like this: your engine is trying to breathe, and the CAI is like giving it a massive gulp of fresh air. A typical stock intake system often pulls air from the engine bay, which, as you know, can get pretty hot. This warm air reduces the engine's efficiency. The cold air intake, however, is designed to pull in air from outside the engine bay. This colder air provides a significant advantage for your engine's overall performance. Typically, a cold air intake kit will include a new air filter, intake tube, and all necessary hardware for installation. The materials used in a CAI are often higher quality than those in a stock system, offering better durability and longevity. There are various types of cold air intake systems available, including those that are completely enclosed, and those that are open-element, each designed to optimize performance based on different factors, such as driving conditions and engine needs.

Now, let's look at the difference between a cold air intake vs. a short ram intake. Short ram intakes (SRIs) are another popular modification. The primary difference is the location from which they draw air. Unlike cold air intakes, SRIs draw air from within the engine bay. This makes them easier to install and often less expensive. However, because they pull in hot air, they don't offer the same performance benefits as a cold air intake. They might provide a slight improvement over the stock system, but the gains are typically less noticeable. On the other hand, a CAI, by drawing in cooler air, is more effective at increasing horsepower and torque. The design and construction of the CAI also play a crucial role. For example, some CAIs are designed with heat shields to further isolate the air filter from the engine's heat. The quality of materials, such as the type of filter and the construction of the intake tube, also impacts the performance and durability of the system. Choosing the right cold air intake involves considering these factors to ensure it meets your specific performance goals and driving conditions.

How Does a CAI Work?

As mentioned earlier, a cold air intake's main purpose is to supply cooler, denser air to your engine. The process begins with the filter, usually positioned in a location where it can draw in the coolest air possible, often behind the front bumper or in a wheel well. This cooler air is then channeled through a smooth intake tube, designed to minimize restrictions, and directly into your engine. The design of the intake tube is crucial. It’s usually made of materials like aluminum or carbon fiber, which are less prone to heat soak than the stock plastic tubes. These materials help maintain the cool air temperature as it travels to the engine. The reduced restriction allows for a more efficient flow of air, which helps the engine breathe more easily. As the engine receives more oxygen, it can burn fuel more efficiently, resulting in increased horsepower and torque. The improved efficiency can also lead to better throttle response, making your Explorer ST feel more responsive and powerful. This simple yet effective process is why cold air intakes are a favorite among car enthusiasts who want to boost their car's performance without extensive modifications. Furthermore, the filter in a CAI is usually a high-flow filter, designed to capture debris while allowing more air to pass through compared to the standard factory filter.
