G-Power has introduced an updated tuning program for the BMW M3. Dubbed the "Sporty Drive TU," the revised performance packages have a modified air intake and a larger air filter. This enables the entry-level SK I supercharger system to develop 520 HP (382 kW).
The mid-level SK II package has a new ASA T1-523 supercharger which replaces the previous ASA T1-522 supercharger. This change helps to enable the model to produce 580 HP (427 kW).
Lastly, the range-topping SK II CS features all the aforementioned tweaks as well as a revised ECU and an additional fuel pump. These modifications allow the 4.0-liter V8 engine to produce 610 HP (449 kW).
Besides the performance packages, G-Power offers an adjustable “GM3-RS” coil-over suspension, a stainless steel sports exhaust system and 20-inch alloy wheels with Michelin high-performance tires.
The tuning packages are currently available and the entry-level SK I kit costs €11,500.
