Dry Cotton Engine Air Filter

The SPT high-flow replacement air intake filter serves as a factory-quality maintenance component for vehicles equipped with the Subaru SPT High Flow Air Intake System. This genuine replacement part, which replaces older part number SOA8431020, is constructed with a cotton filter element in a dry design to optimize airflow efficiency for your engine. Designed specifically to work with the Subaru SPT High Flow Air Intake System (parts SOA8431000 and SOA8431010), this filter is sold as an individual unit. Each kit includes a new worm clamp to facilitate a straightforward installation process, ensuring the filter is properly secured for consistent performance. Fitment is specific to 2002-2007 WRX and 2004-2007 STI models. By replacing a worn-out filter with this OEM-spec element, enthusiasts can maintain the intended intake efficiency and throttle response of their performance intake setup.
