1/2" aluminum spacer plate that raises your blower for improved airflow into the lower intake manifold.

This spacer features an integrated O-ring which eliminates sealing issues and the need for a second gasket. It comes with two 1/8" NPT ports and two 1/8" NPT plugs. They can be plugged, used for methanol injection, and/or an extra vacuum port.

Raising the blower 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.

Includes longer bolts and NPT plugs.
