The Nissan S13 240SX is a beloved platform among car enthusiasts, particularly for its lightweight design and rear-wheel-drive layout. One of the most effective modifications to enhance performance is the installation of a cold air intake system. Injen is a well-known brand in the aftermarket industry, offering high-quality cold air intakes that can significantly improve throttle response and power output for the S13 240SX, all for under $300.
What is a Cold Air Intake?
A cold air intake (CAI) system is designed to replace the factory air intake system of a vehicle. The primary function of a CAI is to draw in cooler, denser air from outside the engine bay, which can lead to improved combustion efficiency and increased horsepower. By reducing the temperature of the air entering the engine, a cold air intake allows for better performance and throttle response.
