Sainz has moved on to a sixth MGU-H in Suzuka, as well as a fifth internal combustion engine and a fifth turbo. The first change comes with a 10-place grid drop, while the ICE and turbo each incur five-place drops.
The Spaniard's penalties were confirmed shortly after a heavy crash in the opening practice session, which caused extensive damage to his Toro Rosso.
Alongside Sainz, several other drivers have taken on new components this weekend - including Ferrari's Sebastian Vettel and Kimi Raikkonen and Mercedes' Lewis Hamilton and Valtteri Bottas. All four are within their allocation of four components for the season, but any further changes would result in grid penalties.
