SLP Air Box Differences?

I know that SLP makes two different CAI. One for the 97-98 with the coolant bottle behind the healdight and one for the 99-+ with the coolant bottle in the upper engine bay.Whats the difference? If i get a 99+ one will it still work?

now let's think about this one for a second... If the 99+ SLP would work on the 97-98... why would they bother to make two seperate set-ups? Common sense man... Quit worryin about buyin a 30 dollar collant bottle and get the intake that fits ur car.
