MODIFYING YOUR CUMMINS?

APP’s Rear BOLT-ON Freeze Plug with O-ring will eliminate a blown or leaking freeze plug due to high rpm and increased internal coolant pressure in modified engines.  It is also tapped with a 3/4 NPT for use of a coolant bypass.  If the factory freeze plug fails or leaks, this part may be installed without the need to remove the transmission!
