Subaru Air Delete
What is Secondary Air Injection?
Secondary Air Injection applies a complicated assembly to feed ambient air into the exhaust path, provoking earlier catalyst initiation. Moisture and other related issues cause this system to malfunction in up to 80% of vehicles aged over three years.
What is the Air System Delete™?
The Air System 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.
