Description
Factory intake valves wear down under sustained high RPM operation, leading to decreased airflow efficiency and compression loss. The Wiseco VIS009 addresses this with surface treatments that dramatically reduce friction while withstanding extreme heat, ensuring your KFX400 or DR-Z400S maintains peak performance across extended riding seasons. Whether you’re prepping for race day or maximizing reliability on the trail, this precision-engineered valve delivers the durability serious riders demand.
