The Lexus IS300 is known for its performance and sleek design, but enthusiasts often seek ways to enhance its power and efficiency. One popular modification is the installation of a cold air intake system. In this article, we will compare two leading brands, K&N and Injen, to determine which one adds more horsepower to the Lexus IS300.
Understanding Cold Air Intakes
A cold air intake system replaces the factory air intake system, allowing for a greater volume of cooler air to enter the engine. Cooler air is denser and contains more oxygen, which can lead to improved combustion and increased horsepower. The two brands we will focus on, K&N and Injen, are well-regarded for their performance enhancements.
