What is this ?

Reminds me of the old days in the sixties so many gadgets to increase horsepower then the next was improve fuel mileage if one installed all the fuel saving devices and added the total alleged savings one became a fuel producer rather then a consumer.

 

That there is a snake oil module!

It probably does have some sort of negligible effect on the voltage stabilization it claims to have, but IMO it’s too small to be noticeable.

 

I am almost tempted to buy one to experiment with if I did not have far to much to do already

 

Opens up a whole new market niche for Chinese knock-offs of Japanese snake oil products

 

Snake Tacos?

 

Disconnect it and donate it to the trash can. You will not notice any difference in gas mileage, horsepower, or how loud your radio is.

 

Save the horsepower by not lugging crap around any more.

The benefits of chucking that crap in the trash.

• Increased fuel economy.
  
• Increased payload capacity.
• Increased performance.
  
• Less emissions.
  
• Women will throw their panties at your truck. Why is that a thing?
  
• Clean spot in your engine compartment.
• Leaves room for mods that are useful.
• Increase reliability
  
• Your friends stop giving you a hard time about snake oil.

Alternatively you cold send it to Wyoming09 for forensic analysis.

 

I would increase fuel mileage by removing all the plunder behind my seats no doubt 500 pounds

I would love to see the print on this to see what it really is.

Now granted the OP has no idea just what it might have been used for.

Every machine I work on has several Caps . When the bigger ones explode they sound about like a M-80.

For some reason they tend to be placed under the control board

 

I gotta wonder does it do anything ??

I would not buy it for any of the reasons it seems to be marketed .

I would think Law enforcement might run something like this for all the electronic gadgets they run

 

They are under the control board to make sure that they are not easily accessed for repair.
