Improved design. 2 pieces in 1 package. Screw it into the weighing block. Effectively moves the main jet's fuel entry point into the fuel bowl. Durable and long lasting.

The jet extension design that actually screws into the meter block has been improved. The main meter jet screws into the end of the extension. The installation effectively moves the main jet fuel inlet into the fuel bowl. In this location, it is not covered with fuel and becomes lean during heavy acceleration and braking.
