Black Pressure Relief Plates





Induction Solutions’ new Black Pressure Relief Plate billet spacers, featuring pressure relief technology, have two functions in a single spacer. You get the power increases of an open spacer and the benefit of the I-S Pressure Relief Plates on all four sides. The Pressure Relief Plate helps relieve pressure suffered during start-up backfire or a nitrous-style backfire.

The Pressure Relief Plate features four spring-loaded panels that are sealed with an O-ring for the best in performance and pressure relief. The panel returns to its original position following a backfire event. There are NO disks to be replaced, NO spare rings required, and NO special tools needed.

The inside diameter of the 4500 spacer is 5″ x 5″

The inside diameter of the 4150 spacer is 3 5/8″ x 3 5/8″
