They can be used on vehicle fuel hoses, on the inlet and outlet of the vapor expansion tubes we sell, on your pcv valve hose, on boiler gas inlets, on water pipes - anywhere where an increase in combustion efficiency is sought, or the benefits of ionization are required. There are too many applications for this to be quoted here. For maximum efficiency - and this is always recommended - you should mount two magnets near each other, as is done in the above photo. It's called a bipolar treatment. So one is north pole, and one is south pole, on the facing side next to the tube/pipe/etc. that you are mounting it on. Doesn't matter what order this is in - whether north/south or south/north. At these prices, buying two of ours – that is with 4 magnets - is not expensive.
Because of the mounting, the magnets are held in place by their attraction to the metal bits. The attachment wraps are reusuable - that is, if you wrap it around something, and want to move or remove it, its easy enough to detach it. The reason we have them mounted as they are, so you can pull the magnets, with some effort, from their mounting, is so that you can reverse the polarity without having to purchase another magnet.
The only disadvantage of not having a protective bottom is if it is used on hot surfaces. We don't recommend you using this on anything that is itself near the boiling point of water. The great majority of applications will not be anywhere near this. One thing to remember - don't put the magnets together! If you do, they will have 26 pounds of pulling power between them to separate, so you could pinch your skin painfully if it was caught between the two. In that case, you would have to use a screwdriver to pry them apart - ouch!
What sort of improvements or fuel efficiency savings can you expect? With 2 of them - one on them on the fuel hose next to each other, as in the picture, and one on the inlet outlet of our expansive tube - we were able to go from 45mpg on our standard intake manifold vaporizer system to 51mpg. The car before we started doing anything got 30mpg. The improvement over the base mpg was a 20% increase! We have obtained this improvement over and over again - this is not a one off example. The mode, rather than the average, is around 15%. And you can also put one of these on your pcv hose, you can most likely get another 5% as well. At the moment, the recommended attachments are fuel line, air intake and pcv hose. So 3 enhancers (6 magnets).
The guarantee with buying one for a fuel line is 10% fuel economy improvement. For the other applications, 5%.
You could just purchase 2 of these - 1 for the fuel line, and 1 on your air intake - without getting anything else, and expect somewhere in the range of 12-15% increase in mpg. You could do this on any vehicle, without an EFIE or lambda sensor simulator - and it would work. And take about 5 minutes to install. The increase to 20% is achievable with our expansion tube in a vaporizer arrangement, because the inlet and outlet constrict all the gases entering and leaving the expansion tube so they are exposed to the strong magnetic fields from the magnets.
As with all our products, if after ordering and trying these magnetic enhancers you are not pleased with the results, after returning them to us we will give you a full refund. This guarantee is for one year from date of purchase. This does not affect your statutory rights.
