Yeah, I mean its the kind of thing where you can totally try it without any consequence.
Any little bottle with a hose to your intake will do. I guess you might have to drill a hole in your intake, but whatever.
I have always wanted to try one. Just take like an airplane liquor bottle and run a tube to my intake.
50cc.nl calls them "power boxes"
The thing is, a lot of people like to poo poo them and say nay, but the question I would prefer to ask is who has tried them and what differences did they see.
