In Australia McLaren introduced two thin, small winglets to the side of the front section of the chassis. While these elements don't noticeably increase downforce, they do act as turning vanes, splitting the airflow directed towards the cockpit. In Montreal and in Indianapolis, these elements were much bigger (inset) and featured a modified rounded, knife-edge profile. These revised winglets are designed to work closely with the new front wing, which was introduced in Spain, to improve the aero balance of the car.
