The N54B30 is a 3.0L inline-six twin-turbocharged gasoline engine produced by BMW from 2006 to approximately 2016. It was the pioneering model of BMW’s modern turbo era (the first production twin-turbo inline-six following the M54). It is renowned for its strong low-end torque, excellent responsiveness, and tuning potential, and was later replaced by the N55. Common part numbers include N54B30O0, N54B30A, N54B30T0, and others.
Our products are exported to various parts of the country, and the customers we have worked with have received unanimous praise. The company has invested over 20 million yuan in high-end remanufacturing equipment imported from abroad and a first-class production team in the country. Our warehouse has a total area of over 8000 square meters, with scientific management and sufficient supply of goods.
