Ilott will drive its #6 Chevrolet-powered entry in place of David Malukas, who is recovering from surgery on his left wrist.
The 25-year-old Briton has already subbed for Malukas – who suffered the injury while mountain biking – in pre-season testing at Homestead-Miami Speedway.
Ilott has made 36 IndyCar starts with Juncos Hollinger Racing over the last three seasons, including five top 10 finishes. He also has experience in Formula 1 as he was a test driver for Ferrari and a reserve driver for Alfa Romeo (now Sauber) in 2021.
“Obviously I feel sorry for David and the team,” Ilott said. “It’s not easy to be in this position especially just ahead of the start of the season. I wish him the best and a speedy recovery.”
The deal is a one-off, as in a statement Arrow McLaren says it “continues to evaluate options for its driver line-up for future tests and races as David recovers”.
