In this article, we will explore the best camshaft brands available for the Nissan 240SX and what to consider when choosing the right one.
Understanding Camshaft Functionality
The camshaft plays a crucial role in the engine’s performance by controlling the timing and duration of the intake and exhaust valves. Upgrading the camshaft can lead to improved airflow, resulting in better combustion and increased power output. When selecting a camshaft for your Nissan 240SX, it’s essential to understand how different specifications can affect engine performance.
