Vitos boost bottle.. ???

Yeah ive heard theyre just for loks but ive heard that some ppl said they made a difference? im just wandering who? my buddy said it did on his banshee but thats alot diff.. plus its beyond built so that might be a factor too...
 
well on a two cylinder motor like a banshee they give a slight very very slight. on any other motor there is no noticeable gain at all not even a bit lol
 
great product............................. filled with some whiskey
