Significant advantages of the DO88 radiator compared to the original:

  1. 28% bigger core volume, 12 893cm3 vs 10 100cm3
  2. Triple pass design, the water is controlled so that it passes the radiator core three times
  3. High efficient core with 5mm fin height of multi-louvred design.
  4. Dual core design, 2 row 42mm thick core.
  5. Easy installation. (See installation instructions linked below)

This radiator is constructed to deliver the best possible cooling efficiency during tough conditions. Exclusively manufactured in aluminium with uninterrupted welds, it guarantees reliability and endurance when you really need it.

The increased core volume improves cooling efficiency and lowers the liquid temperature. Naturally, this being a do88 performance product, we have executed thorough, severe and continuous tests during development of this product to ensure best performance – NO compromise has been made! This radiator is completely optimised to the given space for an easy drop-in-fitment. This is the undoubted choice for the inspired enthusiast or the race car driver demanding reliability at the limit. We take comfort in saying this radiator will fulfil your needs! No more cracked plastic tanks, choose do88 today!

Please note: it is very important when installing this radiator to flush the engine completely to clear all old coolant and refill the system ONLY with genuine Audi coolant (anti Freeze) and distilled water. Failure to do so may invalidate the manufacturers warranty, and lead to premature failure of the aluminium welds. This is because charged particles caused by a mix of coolant types or in tap water can effect the welds of all aluminium radiators over a period of time.
