Partial Grille Block
The front grille of a vehicle is used to direct air directly into the engine compartment. However, this redirects airflow from around the vehicle to through the vehicle, which increases drag. In order to reduce this impact a grille block is often used. A grille block covers up a portion, or all of the front grille of a vehicle. In most high efficiency models or vehicles with low drag coefficients there will be a very small grille already built into the design, therefore a grille block is unneeded. The grille in most production vehicles is built generally to have as much air flowing into the engine in order to keep it from overheating. But most commonly there is too much airflow into the engine, preventing it from warming up in a timely manner, so a grille block is used to increase engine performance and reduce the vehicles drag.

Famous quotes containing the words partial and/or block:
“There is no luck in literary reputation. They who make up the final verdict upon every book are not the partial and noisy readers of the hour when it appears; but a court as of angels, a public not to be bribed, not to be entreated, and not to be overawed, decides upon every man’s title to fame. Only those books come down which deserve to last.”
—Ralph Waldo Emerson (1803–1882)
“Get behind me, Satan! You are a stumbling block to me; for you are setting your mind not on divine things but on human things.”
—Bible: New Testament, Matthew 16:23.
