This is a set of 4 Allstar Performance restrictor plate inserts with a 1.400 in inside diameter (ID), the largest ID in the 1/2in-plate family before the non-restricting Full Throttle insert. They are made of natural-finish aluminum and are sized for Allstar's 1/2 in thick adjustable restrictor plate.
