Mishimoto Expansion Tank - Subaru BRZ (ZC6) / GT86 (ZN6)
Factory plastic coolant tanks get brittle and swell after years of heat cycling, eventually cracking and leaking without much warning. Mishimoto builds this coolant expansion tank from TIG-welded aluminium, giving the Subaru BRZ (ZC6) and Toyota FR-S/GT86 (ZN6) a stronger, better looking replacement that won't degrade the way the stock unit does.
This listing covers the Subaru BRZ (ZC6) and GT86 (ZN6). It's available in Wrinkle Black or Polished finish, select your preferred option from the variant selector on this listing.
