7 Best Cold Air Intakes for Increased Horsepower

Upgrade your intake system for more power. We review the 7 best cold air intakes, comparing their airflow, filtration, and ease of installation. Get the most out of your engine with a high-performance intake.

Understanding Cold Air Intakes and Horsepower Gains

So, you want more horsepower? A cold air intake (CAI) is often one of the first modifications people consider, and for good reason. It's designed to replace your factory airbox and filter with a less restrictive system, allowing your engine to breathe easier. The basic principle is simple: cooler air is denser, and denser air contains more oxygen. More oxygen means more efficient combustion, leading to increased horsepower and torque. But, not all cold air intakes are created equal. Let's dive into what makes a good CAI and which ones stand out from the crowd.

Key Factors to Consider When Choosing a Cold Air Intake

Before we get into the specific recommendations, let's discuss the factors you should consider when choosing a cold air intake:

• Airflow: This is the most crucial factor. A good CAI should significantly improve airflow compared to your stock intake. Look for intakes with larger diameter tubing and less restrictive filters.
• Filtration: While airflow is important, you don't want to sacrifice filtration. A good filter will trap dirt and debris, preventing them from entering your engine and causing damage. Look for filters made from high-quality materials like cotton gauze or synthetic fibers.
• Heat Shielding: The "cold" in cold air intake is important! The intake should be designed to minimize the amount of hot engine bay air that enters the system. Heat shields or enclosed airboxes are essential for maintaining cooler intake temperatures.
• Material and Construction: Look for intakes made from durable materials like aluminum or high-quality plastic. The construction should be solid, with tight seals to prevent leaks.
• Ease of Installation: Unless you're a seasoned mechanic, you'll want an intake that's relatively easy to install. Look for intakes that come with clear instructions and all the necessary hardware.
• Sound: Many people enjoy the more aggressive sound that a CAI provides. However, this is subjective, so consider your personal preference.
• Price: CAIs range in price from a few hundred dollars to over a thousand. Set a budget and stick to it.
