KYOSTAR 4" Cold Air Intake System for BMW G20 G21 M340i G22 G23 M440i G42 M240i B58TU 3.0T

Upgrade your compatible BMW M340i, M440i, or M240i equipped with the Gen2 B58TU 3.0L turbocharged inline-6 engine with the KYOSTAR 4" Cold Air Intake System. Designed as a performance-oriented replacement for the factory intake system, this intake provides a larger and more direct airflow path for compatible B58TU-powered BMW applications.

The 4-inch intake design is engineered to provide a high-flow path toward the turbocharger, while the enclosed intake-shield configuration helps separate the air filter area from the surrounding engine-bay environment. The performance-oriented layout can also make turbocharger and induction sounds more noticeable during acceleration while providing a clean and purposeful engine-bay appearance.

Fitment Note:

BMW M340i, M440i, and M240i intake configurations may vary depending on production year, chassis code, engine generation, regional specification, and factory equipment. Please verify that your vehicle matches the supplied fitment information and is equipped with the compatible Gen2 B58TU 3.0T inline-6 engine before purchase.

The supplied fitment information specifically lists 2019-2024 BMW G20 / G21 M340i, 2020+ BMW G22 / G23 M440i, and 2022+ BMW G42 M240i applications. Other BMW models, chassis codes, or B58 engine generations should not be assumed to be compatible without separate verification.

Please compare the original intake pipe routing, turbo inlet connection, hose connections, mounting locations, and available engine-bay clearance with the product photos. Compatibility should not be determined by the B58 engine family alone, as intake configurations can differ between chassis and engine generations.

Vehicles equipped with aftermarket turbo inlet pipes, upgraded turbochargers, modified charge pipes, or other aftermarket intake components may require additional fitment verification or installation adjustment.

Professional installation is recommended. Proper intake pipe alignment, connection sealing, intake-shield positioning, mounting hardware installation, hose connections, and engine-bay clearance should be checked during installation to ensure correct fitment and reliable operation.
