BMW B58 Parts (M140i, M240i, M340i, M440i)
Parts for BMWs powered by the B58 3.0-litre turbo six: the M140i, M240i, M340i, M440i, X3 M40i and X4 M40i. The engine is shared with the Toyota GR Supra. You'll find B58 downpipes, charge pipes, intakes and chiller systems, plus carbon aero, LED lighting and suspension parts for these models.
Gen 1, Gen 2 and the latest B58TU engines use different parts in some areas, so send us your model, build date and any existing mods and we'll confirm fitment before you order. Supply only, or supply and fit at our Stepney workshop. Looking for the Supra? See our GR Supra A90 parts.
