The Datsun 240Z is a classic sports car that enthusiasts love for its sleek design and performance potential. One of the most effective upgrades for this vehicle is installing a cold air intake system. A well-designed cold air intake can significantly improve engine performance, often providing a boost of 10-12 horsepower. In this article, we will explore some of the best cold air intakes available for the Datsun 240Z, focusing on options from K&N and SR Performance.
What is a Cold Air Intake?
A cold air intake (CAI) is an aftermarket engine component that replaces the factory air intake system. The primary purpose of a CAI is to draw cooler air into the engine, which is denser and contains more oxygen. This increased oxygen supply allows for better combustion, leading to improved horsepower and torque.
Benefits of Installing a Cold Air Intake
- Increased Horsepower: Gains of 10-12 HP are common with quality systems.
- Improved Throttle Response: A CAI can enhance the engine’s responsiveness.
- Better Fuel Efficiency: Cooler air can lead to more efficient combustion.
- Enhanced Engine Sound: A CAI often produces a more aggressive intake sound.
