BMW 4 Series Aftermarket Parts & Performance Upgrades

The BMW 4 Series is defined by its sleek silhouette and athletic stance. Whether you’re driving the original F32 Coupe or the bold, modern G22/G26 Gran Coupe, the 4 Series is the perfect canvas for personalization. At AUTOID, we specialize in high-quality styling and performance components that enhance the natural lines of your BMW while adding a touch of motorsport-inspired aggression.

Precision Carbon Fibre & Styling 

Our 4 Series collection includes premium carbon fibre components that provide an OEM+ fit and finish. Our styling range includes:

• Front Splitters: Give your G22 or F32 a lower, wider appearance with our selection of gloss black and pre-preg carbon fibre lips.

• Side Skirt Extensions: Perfect for bridging the gap between the front and rear of the car, giving the 4 Series a more "planted" profile.

• Rear Diffusers: Available in various designs to accommodate both standard and upgraded exhaust tips, including aggressive M-style finned versions.

• Boot Spoilers: From subtle lip spoilers to aggressive high-kick designs, our spoilers are the finishing touch for any 4 Series build.

Performance & Handling Improvements

To match the sharpened aesthetics, we offer performance hardware from world-renowned brands. Upgrade your 4 Series with Eventuri intake systems for improved airflow, or explore our exhaust and suspension options to unlock the true driving potential of the 420i, 430i, and M440i models.
