This 328d is a sleeper-style project that tightens up a diesel commuter. Darkside Developments parts — EGR block off, swirl flap delete, intercooler and downpipe — clean up flow and reliability, while X Automotive Stage 3 XHP makes the power feel purposeful. KW V1 coilovers with Vorshlag camber plates and Apex Arc-8 wheels sort handling and stance. Subtle interior suede trim, WeatherTech rain guards and Easy Bimmer Apple CarPlay bring comfort and refinement. It’s a smartly engineered blend of endurance mods and tasteful street presence.
