NRW Design Billet Water Pump Adapters - BMW G80 M3 | G82 | G83 M4 | G87 M2 (S58)

The factory S58 water pump uses plastic coolant adapters that can crack or break, and BMW does not supply them separately – meaning a broken adapter normally requires replacing the complete water pump.

The NRW Design S58 Billet Water Pump Adapters are CNC machined from 6061-T6 aluminium as direct replacements for the factory parts, letting you replace just the failed adapter – or upgrade preventatively – with a far stronger component.

Please note: Supplied with new Viton O-rings. We recommend lightly lubricating the aluminium adapter before fitting the rubber coolant hose to help it slide on.
