The mountune Fiesta ST Induction Upgrade includes a uniquely constructed aluminum air box with a secondary cold air feed point. Additionally, the air box has been engineered with features that reduce the delta pressure drop by 2kPa that when coupled with the included K&N air filter, provide a 21% increase in airflow. The mountune Fiesta ST Induction Upgrade provides the foundation for further performance upgrades with an engineered approach that retains the OE appearance and reliability while providing a rich, deep induction note that reflects performance.
