Unleash Iag Coolant Expansion Tank For 02-07 Subaru Wrx 04-07 Sti (black). Tool [BJu3EQds]

The IAG Performance custom aluminum coolant expansion tank is designed for car builders seeking a race like engine bay for their 2004-07 Subaru WRX or STI. By relocating the coolant expansion tank from the intake manifold to the passenger side front strut tower the builder can create additional space for rotated turbo kit piping. Made from 1/8" thick sheet metal aluminum that is precision waterjet cut, bent and tig welded with a -8 AN coolant turbo return fitting, -8 AN drain outlet fitting and .25" barb fitting for the overflow. The tank includes two integrated mounting brackets along with the supplied hardware for an easy installation. Each IAG tank is powder-coated in either red or black and features the IAG logo laser engraved on the side. IAG's custom aluminum expansion tank is designed to reuse your OEM coolant expansion tank cap.
  • Allows relocation of the OEM coolant expansion tank to gain additional fitment, such as for rotated turbos.
