Intake funnels are special funnels that are attached to the air cleaner's intake openings to optimise the airflow. They have a conical shape that reduces air resistance and ensures even distribution of air into the intake duct.
By using intake funnels, the airflow can be accelerated, which can lead to improved engine performance. They can also help improve engine response, especially at low engine speeds.
Intake funnels are available in a variety of sizes and materials and can be selected to suit the motorbike and its intended use. They are often used by motorbike tuners and racers to optimise power and torque. However, it is important to note that changes to the air intake system can affect engine tuning and may require fuel mixture reprogramming or other adjustments.
