The Original Secondary Air Injection System Bypass Kit - Wired
The "Original SAIS Bypass Kit". These kits prevent operation of the SAIS at cold start thus letting you clear your related trouble codes, the CEL and Limp mode. Installs by wiring directly into the IAT/MAF Sensor harness. Click image for more details!
This is The Original SAIS Bypass Kit. These kits prevent operation of the secondary air injection system at cold start. By preventing the SAIS from operating many of the trouble codes, CEL and Limp mode that are associated with a SAIS failure will not return once cleared. This wired version of the bypass kit installs very easily by tapping directly into the factory IAT/MAF Sensor harness. Detailed Installation Instructions are easy to follow and include all needed wire colors and an easy to read wire diagram for proper installation. For those that prefer a more professional and discreet looking installation this easy 6 wire hookup allows the bypass kit to look like it belongs in the engine compartment while being more affordable than our Plug In Version.
Here are the Common Trouble codes that the Standard Bpyass Kit can illiminate:1441, P1442, P1444, P1445, P2440, P2441, P2442, P2443, P2445*, P2447

More About the SAIS Bypass Kit
The bypass module is activated when the ignition is first switched to "ON" and any time it detects a 4-12V signal on the starter relay wire. The starter relay option is only available on the Original SAIS Bypass Modules! This option, when connected, ensures that the module actively prevents the SAIS from running on EVERY start. With the starter relay wire connected you can turn the ignition to "ON" for any period of time and the module will be active as soon as you crank the engine. Without the starter relay wire connection, you would need to turn the igintion back "Off" and then crank the vehicle to ensure the module is active or the system could operate and cause trouble codes and the CEL to come back on. Just install the kit with the starter relay wire connection and don't worry about having to start the engine as soon as you turn the key on! If anyone else drives the vehicle this is a Must!
The included No.2 Exhaust Valve Block-off Plates are an integral part of the bypass kit (images may not match the plates you receive for your specific engine). The block off plates are the only way to isolate the exhaust valves and the related pressure sensor(s) from the exhaust. By completely isolating the system from the exhaust the pressure sensors are prevented from causing valve stuck open trouble codes which are the main cause of limp mode when this system fails. Even though a system is bypass and should never run again, the Exhaust No.2 valves can still leak exhaust and cause future trouble. Installing the block off plates is the only way to prevent future valve trouble and limp mode. Again, it is just best to install and forget about it.

I bought my Tundra used from a good friend, and I knew about the AIP failure beforehand. I ordered the bypass kit but I don't know anything about automotive work, so I had the kit for months before I had a buddy look at it and demystified the location of the valves. I'd been clearing the codes with a scanner and that was fine but it gets old. Finally installed the kit this weekend and drove around several different times and no codes! What a relief. My truck threw a CEL nearly every time I drove it and now it's back to my old powerful beast again. You guys deserve a medal.
Installed on my 2005 Toyota Tundra. Easy install at little over an hour. great product.
We bought this for my father in laws 2006 LandCruiser and it worked perfectly. Paul was incredibly helpful and spent time on the phone with us on Sunday afternoon to knock it out. The directions are easy to follow and if you can change your oil I think you could tackle this job. The fact that you're on this website instead of at the dealer spending $4K means you can tackle this job.
I bought tis unit for my 05 tundra. Plugged it up and it worked great. Not to mention after ordering the unit it showed up the next day. Excellent service and a great product. Thanks
Ordered the module and it came in very quickly. I spent some extra time to make sure everything was well hidden because I still take the truck to the dealership for its regular service. I ended up making all the connections inside the main wiring harness just before it enters the fire wall and extending the wiring so I could mount the module on the passenger's side kick panel inside the truck. I wasn't about to pay the $2700 that the dealership quoted on fixing the system. I would recommend this module to anyone who is having issues instead of paying to fix the obviously flawed system.
Installed plug and play bypass on 2006 Tundra last night. Installed myself in about an hour. Works great better than spending 2K
I ordered your unit for my 2005 Sequoia on Monday after 12:00 had it the next day at 10am that's great service & the unit worked like a charm THANKS for saving me a couple thousand dollars I don't know what else you folks make but I rate this AAA Thanks Jack Ashley
