On one of my usual crawls around the well known comedy site eBay.
I came across this device :
Its "CLAIMED" that this thing can save petrol, being a curious kinda guy I just wanted to ask has anyone seen this or anything similer?
Is there any science behind it?
Or does this belong in the trash like the rest of these so-called performace parts that seem to be shiney and do nothing?
I may buy one to reasearch, well rip apart and totally disprove or prove the so called benifits (I get quite bored you see)
