The Mishimoto X-Line aluminum radiator for 1999–2002 BMW Z3 manual transmissions is an OEM upgrade built from aircraft-quality aluminum with polished end tanks and a multi-row core. Designed to improve cooling capacity over stock, the thicker core and increased row density boost heat rejection and help prevent overheating under demanding driving, making it a durable direct-replacement radiator for supported Z3 models.
