I also have a Toyota, It is an 05 Seinna. My wife is a bit nervous about putting an HHO unit on board. I dont blame her as they are high maintenance. I will put one on for her, I just need to make sure its very stable and wont require her interaction much...lol. She actually drove the other day on a flat tire and didnt even notice it was flat. I drove it on the flat for about 60 seconds and heard and felt the difference immediatly. Shows how observant she is to certain things. Take $5 out of the bank and she catches that right away...lmao
