In short
The B58 is a turbo petrol six. It is in the 340i, 440i, M440i, and newer 540i. It came after the N55 and does not replace it.
The page shows the parts still on the engine. We do not sell a bare long block unless the page says so.
Will it fit my car?
The F30 340i, F32 440i, and G22 M440i do not share every bracket and sump. Buy for your car.

Warranty
Many engines come with up to 12 months warranty. A proper workshop must fit the engine. The warranty is for a fault inside the engine. It does not cover the wrong engine, a dry start, the wrong oil, or damage done after you open the crate.
Shipping
Crate shipping from Hamburg costs 299 EUR. We pack the engine in a strong crate and send it to the address on your order. You need a forklift or an engine crane to unload it.
