Located between mass airflow sensor and throttle body, this is a common item to crack or split over time due to the engine bay heat. A perished intake boot allows unfiltered and unmetered air to enter into the engine that that can cause incorrect air/fuel ratios, resulting in rough idle, poor performance and other engine drivability issues. We offer this OE-Quality replacement from Febi.
