C'est surtout la partie supérieure du capot moteur - au desus de le ligne d'échappement- comme dessiné sur le profil 4, plus arrondi que sur le 3.

I have not been able to find any “official” explanations for this change, but there must have been some good reasons as forward view from the cockpit was limited enough as it was. The modified contour is typically seen on Spitfires Mk. XVI and many Mk. IXe. One hypothesis is that the enlarged upper cowling was introduced in the Mk. XVI design to make room for the modified intercooler of the Packard-built Merlin 266, which in this version of the engine had an integral header tank. The British production Merlin 61, 63, 66, and 70 had a flat-topped intercooler and a separate, firewall-mounted header tank. Of course, once a modified cowling was designed, there was good reason for using it also in the Mk. IX production. In fact, the Mk. XVI was built in parallel with the late Mk. IXs on the same Castle Bromwich assembly line.
