That is all very polite sounding, but it seems the consensus here would indicate they don't work to help MPG. Do you recommend these $125 plugs for people hoping to improve mpg? Even on cleanmpg they did extensive testing and found no benefit, yet your site clearly implies these expensive plugs provide improved mpg ("tired of getting beat up at the pump")?

They don't seem to actually improve mpg from what I can tell, and they are exceptionally expensive for a spark plug. What are your lab testing methods and controls and how did you arrive at your mpg improvement claim before marketing this product?
