Because the 4.0-litre MDG flat-six powering the 718 GTS 4.0 is a naturally aspirated engine from the 9A2 Evo family, forced induction hardware is not applicable to this platform. Upgrading these specific models relies entirely on maximising volumetric efficiency through improved mechanical breathing rather than increasing boost pressure. To extract the maximum performance from your vehicle, we recommend reviewing our intake and exhaust categories to improve airflow and release additional horsepower.
