    Secondary Air Injection System Bypass Kit
    @Koynoel75 The most expensive option is taking it to the Dealership and replacing with Factory/OEM Components. On average, most Dealerships will quote between $2,000 – $3,000 for parts and labor. Depending on your engine size, you may need to replace both Air Switching Valves and could involve removal of the intake. However, replacing the Air Switching Valve only partially addresses the Secondary Air Injection System and even worse may only be temporary. This option does not prevent the other Air Pumps or Valves from failing or even guarantee the new Air Switching Valve from failing again in the future.

    We are more than happy to answer any question you may have about the Hewitt Technologies SAIS Bypass Kits. I have also included some additional resources for any one looking for more information about this issue.
