I have a 2007 Yaris and have been using the Plus Plugs for two years and they work great increasing my gas mil by 5 miles per gallon I get 40 miles per gallon using them 35 not using them not to mention more power. I think what happen to your Yaris was that you already had a weak coil or a manufacture defect. When a mechanic saw my plugs at a check up he said they where a waste of money which I laughed at because I have been testing them for two years with and without. One very important thing to note is not all mechanics know what they are talking about and very afraid of new technology.
