Renault are likely to introduce their version of the F-duct at the Belgian Grand Prix at the end of August.
The French manufacturer lie fifth in the Constructors' Championship with 89 points following a string of impressive performances from Robert Kubica.
However, the team had a tough weekend at Silverstone with Vitaly Petrov finishing 13th and Kubica forced to retire with a driveshaft failure at the rear of the car.
The team though will be boosted by several upgrades, including the F-duct, over next few weeks, according to team boss Eric Boullier.
"The second part of the season will be crucial to see where exactly our pace is and if we can get the best of our car to get some more pace and more podiums," he said on the Renault F1 podcast.
"You always have some inertia, when you have an upgrade on the car the decision to do it and to manufacturer it was done two weeks or maybe three races before. So we still have some good developments coming for the next two, three or four races.
"We obviously have some specific tracks like Singapore, Monza or Budapest where we will have a special aerodynamics package. But we still have some good upgrades including an F-duct coming so that is quite promising for the end of the season. Actually I can't wait to have all this on the car!
"[Its introduction will be] depending on the production, because now we have validated a good package, and depending on the schedule because Budapest is a high-downforce track so we don't need to have it there. Maybe we will get it before but very likely right after."
