The Secondary Air Delete™ is a microprocessor-based solution for removing the problematic Secondary Air Injection system in all late-model Subaru vehicles. The ASD uses an innovative, and intelligent algorithmic approach that is completely self-contained within the unit, requiring no ECU or other modification.

It is not necessary to remove any faulty Secondary Air System component. This product is designed to present the vehicle in a non-modified or altered condition.

No ECU reflashing or error flags disabling is required.

Works with Cobb Accessport & any other devices.

All ECU OBD Status functions remain standard and function as normal including the drive cycle G procedure.
