So I got a great deal on a Wizair intake but also have a 98. Do I have to change to a 99+ coolant bottle? There's absolutely no way that the box will fit over the one I already have? And is there a write up anywhere on how to do the switch? I looked through the how to section and used the search feature but wasn't able to find anything. Maybe I overlooked it but if not could someone give me a walk through on how to do it? Thanks.
