Description
The Holley Standard Main Jets are precision-engineered metering orifices designed to control fuel flow into the metering system. Rated in flow capacity cubic centimeters per minute, these jets are changeable for tuning purposes. The shape of the entry, exit, and size determines flow. All Holley Main Jets are flow tested and then stamped with the correct number. This pair features a 0.053-inch jet size and 1/4-32 thread, suitable for various Holley carburetor models.
