A Durable Aluminum Alternative to the Factory Plastic Adapters

NRW Design developed the BMW S58 Billet Water Pump Adapters to provide a stronger, more cost-effective alternative to the factory plastic water pump adapters.

S58 owners regularly encounter broken or damaged factory water pump adapters, and BMW does not offer these plastic adapters separately from the water pump assembly. If an adapter fails, the traditional fix can mean replacing the entire water pump (roughly $500–$600), only to get another pump with the same plastic adapters.

CNC-Machined from 6061-T6 Billet Aluminum

Both small and large billet adapters are precision machined from 6061-T6 aluminum as direct replacements for the factory components, maintaining factory dimensions and fitment. Instead of replacing an otherwise functional water pump, you replace only the failed adapter.

Features & Benefits

  • Direct replacement for the OEM S58 water pump adapters
  • Precision CNC-machined from 6061-T6 billet aluminum
  • Small and large adapter configurations
  • Matches the dimensions and fitment of the factory component
  • Simple plug-and-play installation
  • Includes new Viton O-rings
  • No need to replace a functional water pump because of a broken adapter
  • Stronger, more durable alternative to the factory plastic design

Installation note: Lightly lubricate the aluminum adapter before connecting it to the rubber coolant hose so the hose slides on more easily.

Designed and manufactured by NRW Design in the USA.
