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:
“The only coöperation which is commonly possible is exceedingly partial and superficial; and what little true coöperation there is, is as if it were not, being a harmony inaudible to men. If a man has faith, he will coöperate with equal faith everywhere; if he has not faith, he will continue to live like the rest of the world, whatever company he is joined to.”
—Henry David Thoreau (1817–1862)
“For Jews demand signs and Greeks desire wisdom, but we proclaim Christ crucified, a stumbling block to Jews and foolishness to Gentiles...”
—Bible: New Testament, 1 Corinthians 1:22-3.
