The GEN-II SAIS Bypass Kits Are Here!
Available now for:
4.0L, 4.6L and 5.7L(including Flex Fuel) Toyota/Lexus vehicles of all years.
The Gen-II kits include the module, vehicle specific harness, pair of exhaust block off plates, stainless mounting hardware, Free Priority Mail Shipping and as always, our excellent customer service and Limited Lifetime Warranty! The Gen-II kits don’t stop the system from running like our current V3 and V5 units, they emulate it. The secondary air injection system monitor will even show as complete/ready even with the entire system removed from the vehicle. You can remove the air pump(s), pluming, air injection control drivers and by adding Pressure Sensors Options (PSO) you can also remove the air switching valves. (PSO are also needed if you have damaged pressure sensors) Call us for details and to place your order before they are available for sale to the public on our website!
Gen-II kits are $450 and PSO options are $145 each.
Like all of our bypass kits these are sold for off-road or competition use only!
Like some of the others, I bought my Gen II prior to installation instructions, however, Becky walked me through every step and question I had. I live in TX, did the install and made a 2wk long hunting trip in mountains of Colorado. The Gen II worked flawlessly at all altitudes and in all early morning temperatures, CODE FREE!
And honestly, my 2012, 5.7L Tundra, seems to be a little peppier, maybe a little quicker, haven't check it yet, but maybe a little better fuel mileage. VERY pleased customer here! Definitely 5 stars!
Thank you Becky and the gang!
I was looking at facing thousands of dollars in repair costs and was not about to do that. I did some research and found this product online and after looking at multiple videos and reviews I decided to check it out. I'm very glad I did it's a great product and save me a lot of time and money. I highly recommend this bypass as opposed to paying through the nose at the dealership. Thanks again guys for all the help.
I installed one of the gen 2 kits before there were even instructions . I installed the plates as well which is a bit tricky . The system did work and is still working fine. I recommend some dummy plug covers for open connectors but over all it's a good solution for a big problem .
The Gen II SAIS by-pass has been installed for about a month now. The 4runner is running without throwing a code or going into that darned limp mode. I luv it!!!
Installation took less than 30 minutes, and if you ever had to install a 2nd one, likely install in under 5 minutes.
My 4runner is a "project car" (and daily driver); I bought it as a salvage car, having gone (entirely?) underwater during TX Hurricane Harvey. Over 10,000 miles on the car since placed back in service early last year. The SAIS, one of a number of minor electrical issues, now being sorted out.
