Force India adopted a double snorkel airbox on the VJM07, a solution origins on Mc Laren back in 2011. That design offers a less draggy bodywork behind driver’s head compared to Toro Rosso, but increased air disruption on the rear wing.
Airbox on M03 is very effective in regards of cooling. Beyond the main triangular inlet, there are two more additional openings to cool down internal mechanical parts ( i assume them to be the oil radiator and ERS components). Exploiting airbox zone allows mechanics to maintain sidepod inlets close to 2013 dimensions rather than enlarging them a lot. The appearance of the car now lacking the sculpted bodywork behind the driver’s head resembles more to monocoques prior to 1997 season . Worth’s taking into consideration that such a configuration is more draggy and suffers increased negative aero impact caused from driver’s helmet .
Finally a small but important cooling inlet exists where the engine cover starts to drop downwards to feed the gearbox radiator.

5.blade style roll hoop structure
Team Lotus T128 has a blade roll hoop similar to the one pioneered by Mercedes W02 car last season but thicker to meet with 2012 technical regulations . The benefits of this structure are a lower centre of gravity and a cleaner flow of air towards the rear wing because there is less frontal surface above driver’s helmet . As a result of it the airbox inlet is split into two primary hoses (No1). Formula 1 cars use a pyramidal carbon made air intake chamber to draw air above the driver helmet to feed engine with air. Additionally there are two smaller ones (No2) lying lower to provide gearbox radiator with fresh cooling air .
