Compatibility & Fitment — Thermostat Housing (Aluminium Upgrade)

\n
• Outlet orientation & number of ports (heater/degas/turbo return)

\n

\nTherefore, send your VIN, engine code (e.g., Z16XEP, A16XER, Z18XER, F16D3), and clear photos of your old housing (all ports and sensor boss) so we match the exact unit. \n
