Fitment Note:

This turbo inlet pipe is specifically listed for compatible BMW applications equipped with the Gen1 B58 3.0T turbocharged inline-6 engine. The supplied fitment information covers selected BMW F-Series and early G-Series applications including M140i, M240i, M340i, M440i, 540i, 740i/Li, X3 M40i, and X4 M40i.

Compatibility should not be determined by the B58 engine name or 3.0T displacement alone. BMW produced different B58 generations and turbo inlet configurations, including later B58TU applications that may use different turbocharger connections, inlet geometry, auxiliary ports, and surrounding intake components.

Please verify the vehicle production year and chassis code together with the engine generation. Particular attention should be given to vehicles produced near B58 generation transitions.

Compare the original turbo inlet shape, connection diameter, turbocharger connection, intake-side connection, auxiliary port location, mounting arrangement, and surrounding engine-bay clearance with the product photos before purchase.

Vehicles equipped with upgraded turbochargers, aftermarket intake systems, custom turbo inlets, or other modified intake components may require additional fitment verification or installation adjustment.

Professional installation is recommended. Proper inlet positioning, connection alignment, sealing, clamp installation, auxiliary connection routing, and surrounding-component clearance should be checked during installation.
