The STI Air Cleaner Element is designed for Group N Rally Competition. The element has greater dust collecting performance than the standard part. A stainless wire mesh is also used to reduce distortion of the element under high negative pressure when the vehicle is used in dusty conditions. A double seal gasket is incorporated to improve seal with the airbox. The high tech appearance of the element enhanced with the appearance of the STI logo. Note: This is a competition part. Fittment of this part may affect the durability and warranty of the air flow meter.
