BMW G90 G99 M5 Billet Coolant Reservoir

S63TU5 Billet Coolant Reservoir, BMW – G90 M5

Billet reservoir designed and machined in house to remedy the failing stock plastic reservoir. Our all metal construction reservoir ensures leaks are not an issue anymore. Constructed of 6061 billet aluminum, you know you have a lifetime product and don’t need to worry about leaks anymore. Utilizing the stock cap also retains the pressure bleed off like designed by the OEM. All of the OEM connecting points are utilized and the quick connect fittings slip right on. This is a plug and play solution which even utilizes the stock sensor ensuring there won’t be any issues with level readings.
