Hewitt Tech is the Home of the Original Secondary Air Injection System (SAIS) Bypass Kits for Toyota & Lexus vehicles. These kits offer a cost effective solution for the failure prone SAIS found on certain Toyota & Lexus trucks and SUVs. The bypass kit and kit addons can prevent many of the trouble codes caused by mechanical or electrical failure. Most common failures occur in secondary Air Pumps, Air Switching Valves and Air Injection Drivers. On average, replacing the Secondary Air Injection System can cost between $2,000 - $3,000. Unfortunately, even if you decide to replace these components it is likely you would run into the same issues in the future. That said, if you want to get out of Limp Mode, turn off your Check Engine Light, avoid future failures and save thousands of dollars; a Hewitt Tech Secondary Air Injection Bypass kit is what you need. Our products are made in the USA at our Headquarters located in Lexington, SC and we ship both domestically and internationally. We welcome your questions and encourage you to contact us; Hewitt is here to help you find the right solution.
