Hewitt-Tech

Welcome to the http://www.Hewitt-Tech.com YouTube channel. The videos here will help you understand and install our Secondary Air Injection System Bypass Kits that we offer for certain Toyota/Lexus vehicles. Our bypass kits prevent operation of the failure prone SAIS which will let you clear certain related trouble codes, the CEL and keep you out of "Limp Mode" as well as save you $2000-$3000 on repairs. We currently offer hardwired and plug and play units for the 05-07 model years and a double harness plug and play unit for the 08-14 model years as well as pump replacement packs that will will let you clear additional codes without having to replace a bad SAIS pump motor. Stay tuned for more videos and please contact us if you have any questions or would like to order.
