BMW S58 Water pump connectors – adapters – 11518054857 – 8054857

These aluminum adapters are a stronger and more affordable replacement for the factory S58 water pump adapters. Normally, if the original plastic adapters break, the only option is to buy a whole new water pump, which can cost $500-600 USD.

These new adapters are machined from aluminum, match the factory shape and size, and come with Viton O-rings for proper sealing. They install just like the originals and provide a much more durable solution without replacing the entire pump.

Note: Lightly lubricating the adapters can make it easier to slide them into the rubber hoses.
