20-12602540 GM Coolant Plug - Used when converting from LS1 style intake to LS6 or LSX style intake. (2 required)
20-12602544 GM Coolant Crossover Pipe - Used when converting from LS1 style intake to LS6 or LSX style intake.
This will duplicate the setup on LS6 cars. You do not need the coolant seals with the new style plugs and crossover tubes we carry.
Thanks,
Shane
