The M340i here takes a subtle-but-meaningful approach: Kies Motorsports MST intake wakes up the engine with crisper throttle and slightly more power, while carbon mirror covers and smoked sequential turn signals give the exterior a refined, stealthy look. It's the kind of build that improves day-to-day drivability without shouting. Clean aesthetics, a sharper intake sound, and tasteful touches make this car feel more connected and a touch sportier — great for someone who wants performance upgrades that still look OEM-plus.
