A lot of cars have active grille shutters now so probably. Porsche uses them on the 992 Sent from my iPhone using Tapatalk |

Does it help the engine come up to temp faster?

Better aero for slightly improving mpg.

They are also used to help cars warm up faster because engines are more fuel efficient and produce less emissions at normal operating temps than during cold startup.
The Focus ST had them. At an autocross on a hot day, I developed a near-overheating issue that I discovered was caused by 1/2 (or 1/4?) of the shutters being stuck closed. The arm operating that half (or quarter) had gotten stuck or maybe jumped the gear controlling its motion (hard to remember now) that left it closed. With air temps in the low 90s, 45 seconds of intense use was enough to raise the coolant temp about 40 degrees.
