The ZZP 1/2" aluminum spacer plate raises your blower 1/2" for improved airflow into the lower intake manifold. The spacer features an Oring which eliminates sealing issues and the need for a gasket between the blower and spacer. It has two 1/8" NPT ports. They can be plugged, used for methanol injection and/or an extra vacuum port.

Raising the blower 1/2" will affect the belt length required. A smaller pulley must be used or your stock belt will be too short. A stock belt will work with pulley sizes 2.7-3.0. To run 2.6" or smaller pulleys you will want a shorter belt, larger tensioner pulley or our adjustable tensioner.
