Gen-I SAIS Bypass Kits (Old Style)

Gen-I SAIS Bypass Kits (Old Style)

The Hewitt-Tech Secondary Air Injection System Bypass Kits offers a cost effective solution for the failure prone Secondary Air Injection / Induction Systems found on certain Toyota truck and SUVs. There are many different failures that can occur with this system and these bypass kits are able to prevent the system from operating and triggering many of the trouble codes that will set the CEL or put the vehicle into ""Limp Mode"". When used in conjunction with any needed kit addons the kits can take care of some of the most common codes like :P0418, P0419, 1441, P1442, P1444, P1445, P2440, P2441, P2442, P2443, P2445, P2447

*a description of the codes the kits can typically clear by themselves and the ones that need extra kit addons can be found on our our "Codes" page.

When properly installed our modules will bypass the operation of a faulty secondary air system permanantly and isolate the system from the exhaust. The bypass module prevents the system from operating and the block off plates prevent limp mode and codes associated with stuck valves. Our modules will also allow the installation of off-road or performance exhaust systems that do not have the necessary air injection tubes on the manifold or header to connect to the system.

Please also check out our Codes Section for a full list of codes with descriptions and our Installation Instructions page for more information or use the Contact Us page to ask any questions you may have before ordering.
