Alpine replaced the exhaust of its single-seaters this Saturday on Alonso and Ocon’s cars. This is the 6th component changed this season for Alonso and the 5th for Ocon.
The FIA allows for the use of 8 different exhausts per season. Alonso and Ocon are therefore still within the limit with 8 races remaining in the season and have no penalties.
No other team has announced any changes this weekend regarding power units (thermal engines, electric motors, batteries, electronic boxes, and exhausts).
