Stock Coolant bottle for the 99+ Grand Prix.
The 1999 and up Grand Prix have their coolant reservoir on the passenger strut tower brace instead of being mounted behind the drivers side headlight.
This newer style coolant bottle is sold as an upgrade for '97 & '98 owners. It will allow room for an aftermarket air box. It is needed for the CSC kit in older 97/98 GPs.
