The BMW M Performance Power and Sound Kit is engineered to unlock the full potential of B58-powered BMW models, specifically the F30 340i and F32/F33/F36 440i variants. This comprehensive upgrade includes a performance-tuned engine software upgrade that boosts power by 35 hp, bringing the total to 355 hp, and increases torque by up to 39 lb-ft (369 lb-ft peak for automatic, 355 lb-ft for manual transmission vehicles).
