Is this possible
 

I was reading import tuner and noticed this new product.
Grounding wires that give horsepower


Ground wires

they won't give you any horespower at all. however, if your engine is running poorly because of a bad ground, I.E. bad spark, and you install this wire..or any $2 ground wire for that matter, it'll return it back to its original performance, or there 'bouts.

all it is is a fancy looking wire to make someone some money.
