I am from Coimbatore. There is a guy here near 100 feet road(behind kalyan jewellers) who is selling and installing the hydrogen kit(so called). I went for it for my Spark by paying Rs 12000/ last october. He assured an improvement of minimum 33% fuel efficiency.
I believed it so strongly as I went through several websites about the technology. He also demonstrated. You know what ultimately I didn’t any improvement. He again checked and told that there is some problem in amount of Hydrogen generated. He changed some chemicals and added some more. Again no use. I checked it for nearly 6000 kms. No use at all. I really went in pain in maintaining the kit by filling water every 150 kms. Checking for bubbles(hydrgoen.), etc.
Eventually it started producing a kind of brown color in my airfilter and I noticed a small jerk in my engine’s pickup. I felt this guy has cheated me. I returned the kit as he assured that if there is no improvement in the mileage, you get refunded. Now he took the kit and telling that I can go for some advanced kit. I said no more. I am waiting for refund(partial, if not fully). He is escaping from my calls. My dear friends, be alert. He claims that he is the only one doing in Coimbatore. His name is Sam. if you guys advice me how to get my money, I will be thankful
