AC Schnitzer ACS3 Conversion Kit for BMW F30/F31 340i/xDrive B58 M Sport (2014-2019) – 380hp Performance Upgrade, Carbon Fibre Aero, Sports Exhaust, Lowering Springs, 20in Wheels – Genuine with Warranty

AC Schnitzer ACS3 Package for BMW 3 Series F30 F31 340i and 340i xDrive

Unlock the full potential of your B58-powered 3 Series with the authentic AC Schnitzer ACS3 upgrade. This carefully curated programme elevates power to a verified 380 hp, sharpens chassis response, enhances road presence with premium carbon fibre styling, and adds a richer, sportier exhaust tone. It is the definitive OEM-plus enhancement for the F30 saloon and F31 Touring, engineered in Germany for daily drivability and weekend thrills.

We have installed this package and it is outstanding. Throttle response feels crisper, mid-range torque is stronger, the ride sits lower and more controlled, and the sound is purposeful without drone. Our customers consistently praise the quality, fit and finish, and the way the car looks and drives once complete.
