Upgrade-Water pump for all 2.5L TFSI engines as installed in the Audi RS3 and TTRS. Improved wheel made of metal instead of the vulnerable plastic. The problem with conventional water pumps is that the plastic wheel can come off the shaft. This causes the water pump to fail completely and the engine to get hot. This can cause major engine damage! Our RACE water pump has a solid metal wheel to eliminate this problem. Complete unit with O-ring. Does not fit with DAZA and DNWA Made in Germany Manufacturer Information about the manufacturer BAR-TEK BAR-TEK Motorsport GmbH Im Rauschen Auel 3, 51491 Overath-Brombach, Germany info@bar-tek.com
