Keep a detailed record of all maintenance performed. This is invaluable for troubleshooting and for maintaining the vehicle’s resale value. When in doubt, always refer to your owner’s manual or consult a certified BMW technician.

Popular Performance Upgrades

The B58 engine is highly tunable, making the M440i a favorite for performance enthusiasts. Even subtle upgrades can yield significant results.

Always research thoroughly and choose reputable brands when considering modifications.

1. ECU Tuning (Software Tune): This is the most popular and effective upgrade, unlocking substantial horsepower and torque gains from the B58 engine. Options range from simple “piggyback” modules to full ECU flashes.
2. Intake System: Upgrading to a high-flow intake can improve throttle response and engine sound. Look for reputable brands that offer good filtration and proper heat shielding.
3. Exhaust System: An aftermarket exhaust can enhance the exhaust note and potentially reduce weight. Options range from axle-back systems to full cat-back systems.
4. Suspension Upgrades: For those seeking even sharper handling, lowering springs or coilovers can reduce body roll and improve aesthetics. Ensure any suspension changes are compatible with the Adaptive M Suspension if you wish to retain its functionality.
5. Brake Upgrades: While the M Sport Brakes are excellent, track enthusiasts might consider upgraded pads, rotors, or even a big brake kit for sustained high-performance use.

Always consider the impact of modifications on your warranty and local emissions regulations. If you’re unsure about installing a performance part, it’s always best to seek professional installation from a shop experienced with BMWs. Modifying your vehicle incorrectly can lead to costly damage or safety hazards.
