I did some searching tonight, and it seems the prime benefit of the grille block is the faster warm up time and higher operating temps...which means the engine is more thermodynamically efficient?

I can say though that around town throttle response is noticeably better with the grille bock in place & warmer IATs.
Interesting on the throttle response, and the fact your IAT went up.
