Ive seen them on ebay loads of times, they go for about £40 and apparently save you 10% to 15% in petrol and increase horsepower! Now Im a bit sceptical how something that reduces the flow of petrol could increase your horsepower. Its also apparently better for the environment and can save you money on servicing costs. hmmmmm
I know what your thinking.... and yes I think it can even make you a cup of tea as well! lol
They even offer a money back guarentee. Now Im thinking, well if this thing is so great, why arent car manufacturer installing them as standard.
