LT4 Restrictor


The LT4 Restrictor is used for GM LT4 and 2.0T applications.

SKU: A1604 Category:


The LT4 Restrictor is provided to duplicate the function of the flow restrictors that are built into the LT4 barbs on the bottom of the supercharger.
Since we are re-routing the PCV evacuation from the bottom of the supercharger, it is necessary to substitute a restrictor in the line going from the center valve of the catch can to the driver’s side valve cover.

Please note, these are included in the hardware kit provided with catch can kits for the Corvette Z06.
