These Holley main jet extensions feature a new design that actually screws into the metering block. The main metering jet threads into the end of the extension, moving the fuel entry point for the main jet out into the fuel bowl. When it's in this location, it cannot be uncovered preventing a lean condition during periods of extreme acceleration or braking.
