The Subaru WRX is known for its performance and tuning potential. One of the most effective upgrades for boosting horsepower is a cold air intake system. In this article, we will explore the best cold air intakes for the Subaru WRX, which can safely enhance power by 15-20 HP.
What is a Cold Air Intake?
A cold air intake (CAI) is an aftermarket accessory designed to improve the engine’s airflow. By drawing in cooler air from outside the engine bay, a CAI increases the density of the air-fuel mixture, allowing for better combustion and more power. This upgrade is popular among WRX enthusiasts looking to enhance performance without sacrificing reliability.
