Main Jet Extension 1969-pontiac-grand-prix-esi1241202 Bed Mat - X-Mat -An improved jet extension design that actually screws into the metering block. The main metering jet then threads into the end of the extension. The installation effectively moves the fuel entry point for the main jet out into the fuel bowl. In this location it cannot be uncovered by fuel, causing a lean condition, during periods of hard acceleration or braking. 2 Pkg.
