all it is is a little c02 cartridge that when your carb is poened WOT it turns on the switch which pokes the hole and then it sends a boost of air for more top end, they actually work but are a waste of money theyre like 15-20 dollars for a refill and they only work once and only last a few seconds, so just spend your money alsewhere
