i understand the theory of a boost bottle. i just agree with alot of the foru members on i don't see how it can effectively recharge or discharge being a closed container and relying on vac to charge and discharge.. i would skip the boost bottle, especially since you need to upgrade your intake with an intake made to support a boost bottle. however, since i bought an intake for my son's 90 that had the adapter built in, i may grab one and see if i like it. if i don't like it, i'll dump it off on ebay for half price BIN.
