Description
do88 DO88-KIT133S black radiator hose kit is designed for 1998-2002 Audi S4 and RS4 2.7L BiTurbo B5 applications. These hoses replace factory radiator hoses that can become soft, cracked, or leak-prone over time. It is a useful cooling system upgrade for stock, tuned, and high-boost 2.7T builds needing stronger hose reliability and clean black engine bay styling.
