Kimi Andrea Antonelli will serve a penalty at his home race at Monza
His team-mate Kimi Andrea Antonelli was also awarded a five-place grid penalty after it was reported he had dry ice pellets coming out of his car during the Formation Lap at Spa.
Antonelli had already been noted for a similar incident at Silverstone where he was given a suspended penalty, which has now been triggered.
The Mercedes youngster will also serve a five-place grid penalty alongside his team-mate in Italy in a further blow to Prema who have underperformed this season.
