When This Plug Is Needed
The factory BOV on the 2015-2021 WRX is a recirculation type that returns boost pressure back to the intake. When replacing it with a vented BOV or deleting the recirculation port, the factory recirculation port must be plugged to prevent a boost leak.

Direct-Fit Solution
IAG’s plug is machined to fit the factory recirculation port directly, providing a secure seal without fabrication or custom solutions.

FA20 WRX Application
Designed specifically for the FA20 DIT engine in 2015-2021 WRX applications.
