The Honda Civic Si has long been a favorite among car enthusiasts for its performance and tuning potential. One of the most effective upgrades you can make to unleash additional horsepower is by installing K&N Performance Individual Throttle Bodies. This article will explore how these throttle bodies can help you unlock 15-20 horsepower in your Honda Civic Si.
What are Individual Throttle Bodies?
Individual throttle bodies (ITBs) are a performance upgrade that replaces the factory throttle body setup. Instead of a single throttle body controlling airflow to all cylinders, ITBs provide each cylinder with its own throttle body. This design allows for better airflow management and improved engine responsiveness.
