Max Verstappen's engine parts have also been replaced for the Belgian Grand Prix. However, the Dutchman will not receive a penalty for that.
The FIA have revealed the parts changed or replaced since qualifying under parc fermé.
Earlier today, it has been announced that Lewis Hamilton, Kimi Antonelli and Fernando Alonso will have to start from the pit lane because of the new power unit components on their cars.
The list by FIA reveals that Max Verstappen's RB21 was also fitted with a previously used ICE, turbocharger, MGU-H, MGU-K, and parameter changes associated with the PU elements replacements were also taken into account.
However, unlike in the previous two seasons, Verstappen will not receive a grid penalty as a result of these changes.
