Force India has become the latest team to incorporate a F-duct style concept in its 2010 formula one car.
After McLaren pioneered the rear downforce-stalling innovation this year, teams including Ferrari, Mercedes, Williams and Sauber have followed suit.
The already-dominant Red Bull is also expected to debut an F-duct this weekend in Turkey, as will Force India.
The Silverstone based team said on Thursday that the version for the VJM03 car is called a switchable rear wing or SRW.
“Should be a good improvement,” Force India said on its official Twitter.
Vitantonio Liuzzi told reporters at Istanbul Park that he and teammate Adrian Sutil will activate the flow of air through the engine cover and rear wing slot by covering a hole in the cockpit with their wrist.
“The target is to get into Q3 and then score points,” he said earlier this week.
“We deserved to have a double points finish earlier than Monaco, but for some reasons it didn’t happen, so we need to continue to put both cars the top 10 if we want to catch Renault.”
Ferrari, on the other hand, has modified its initial Barcelona-spec F-duct for Turkey so that the drivers block the inlet with their knee rather than their hand.
It is believed Felipe Massa is particularly happy with the change, given that in Spain he had to move his hand further than Fernando Alonso to block the inlet due to the position of his steering wheel.
