- Description:
Genuine Audi Radiator Upper Insulator is a genuine OEM mounting component designed to secure and cushion the top of the radiator on Audi A4, S4, RS4, and A6 models across a range of engines including the 1.8L, 2.0L, 3.0L V6, 3.2L, and 4.2L V8. This insulator fits both the A4 and S4 main radiator applications as well as the RS4 main radiator, providing a precise, factory-engineered fit that aftermarket alternatives simply cannot match. This part absorbs vibration and prevents metal-to-metal contact between the radiator and the vehicle's support structure, protecting the radiator from stress fractures and premature failure. Because radiator insulators must conform exactly to the mounting geometry of each specific Audi platform, OEM construction matters — aftermarket versions frequently use inferior rubber compounds that harden, crack, or compress unevenly over time, leading to radiator movement and potential coolant line stress. The genuine Audi part 4B3121276A maintains its original durometer rating and dimensional accuracy throughout its service life. Whether you're searching for an Audi A4 S4 RS4 A6 OEM Radiator Upper Insulator, a Radiator Upper Mount, or a Radiator Mount Bracket under part number 4B3-121-276-A, this is the exact component Audi specifies at the factory. Audi Henderson is an authorized Audi dealer, and this part is backed by the manufacturer's warranty for complete peace of mind.
