Ferrari has fitted a new MGU-K to both Charles Leclerc and Carlos Sainz's cars ahead of British Grand Prix qualifying.
Both drivers have taken on their third relevant component at Silverstone after Leclerc hit issues on Friday, with each car on the grid allocated four for the season.
The Monégasque lost valuable track time when unable to exit the pits in second practice as the Scuderia worked to resolve an electrical issue on Leclerc's SF-23.
Leclerc indicated 'everything wrong' had been changed on his car, insisting there would be no issue pre-qualifying.
Ferrari is in the midst of a mini-resurgence having finished second-fastest at the Austrian Grand Prix last week, with its latest batch of upgrades providing better consistency between stint lengths and tyre compounds for its two drivers.
