Liquid Cooled Aluminium Transmission Oil Cooler for Audi A8L D3
The MAX NOLOGY Audi A8L D3 Transmission Oil Cooler is a 100% new, liquid-cooled aluminum cooling solution designed to protect automatic transmissions from heat-related wear. Engineered to meet OEM standards, it’s a direct replacement for select Audi and VW applications, including the A8L D3 lineup, Passat B6, and Phaeton models. With a compact 21.5 x 15.5 x 12 cm profile and brazed cooling fins, this oil cooler efficiently transfers heat away from transmission fluid, helping maintain smooth shifting and longer transmission life even under demanding driving conditions.
When heat management matters, this oil cooler makes a real difference. By keeping transmission oil within optimal temperatures, it helps prevent fluid breakdown, reduces the risk of slippage, and supports consistent performance during heavy city traffic, long highway stints, or high-performance driving. The aluminium construction provides a sturdy, lightweight solution that resists corrosion while delivering reliable cooling for automatic transmissions.
All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
