i know alot of people that spray into there Cobra's pre-supercharger. there is no harm in doing that. plus it will be way cheaper than buying a direct port kit.

everything that is needed wil probably come with the kit, but it is always a good idea to use a window switch and a WOT switch. other than that the warmer, purge, etc is all just nice things to make the kit a little better.

warmer and remote botle opener is not a neccessary but make the kit work better when they are used.
