A used OEM auxiliary/secondary radiator, Audi part number 8E0121212H, was removed from a donor vehicle. These secondary radiators provide extra cooling capacity for high-output engines such as the 2.5L turbocharged five-cylinder in the TT RS Quattro and the 4.2L V8 in the RS4. When the auxiliary radiator develops a leak or clog, coolant temperatures can rise under load, reducing performance. This genuine part mounts on the left or right side and helps maintain proper thermal management on these RS models.
