2004 - 2008 BMW 3 Series E90 Saloon ( Sedan ) PreLCI tuning parts and accessories
The E90 marked a significant evolution in the 3 Series lineage with its athletic stance and increased dimensions, offering more interior space without a significant weight penalty. It was the first 3 Series to introduce the iDrive system, enhancing the driver's control over vehicle settings, navigation, and entertainment functions. The E90 also debuted run-flat tires, eliminating the need for a spare tire and contributing to its near-perfect 50:50 weight distribution. Engine options ranged from efficient four-cylinders to powerful six-cylinders, including the introduction of a turbocharged petrol engine in the 335i model. The suspension system was completely new, with a multi-link rear and an aluminum front, mirroring the 5 Series for improved handling and stability.
