Can someone tell me what it exactly is and what it does, How much performance is gained buy one, and what the best brand is?

 

Do not buy a boost bottle. They dont do anything really, just an unnoticible increase in throttle response. Ive heard from smart guys who say they are just scams. They collect sand and dirt, and people dont really believe in them anymore. Last week, I was looking at a banshee for sale and the guy was looking for something in a drawer, he came across a boost bottle and tossed it on the cement in front of me. He told me how usless it was, then he threw it away.

 

That's interesting, anyone else have any experiance with this?

 

They are a waist of money for performance gains, but i put one on becouse its Purty.

 

ya they arent worth anything. actually my friend who had one had more problems with it then without. his rubber manifolds kept tearing.
