For GT4 racing in Europe, BMW Motorsport insisted on zero failures of the E90/E92 M3 cooling system. This Genuine Motorsport M3 GT4 water pump has an aluminum impeller to replace the standard composite plastic. While the composite pump has proven to be reliable and not a source for failures on street cars, Motorsport engineers felt that metal would eliminate all chance of the pump breaking down. While a little heavier than the standard pump, the assurance of reliability outweighs any minor power loss. GT4 water pump upgrade fits all 2008-2013 E90, E92, E93 M3 with the S65 V8 engine.
