Keep your cylinder head freeze plugs from blowing out when running turbochargers with high amounts of boost, potentially causing high internal cooling system pressures.
Includes 4 freeze plugs, and mounting bolts (enough for both cylinder heads - front and rear)
Install the retainer plates over the top of the existing freeze plugs in your heads. These can be mounted on the front and rear of each cylinder head
Note - check to make sure you have adequate clearance for mounting these plates before purchasing
