Our Billet Aluminum Freeze Plugs Allow you to run your factory fans without blowing your oem freeze plugs under big boost, high pressures, and high RPM.
3 Billet plugs to replace your OEM Plugs on the side of the Cummins block. All our Billet Freeze Plugs have the Viton Rubber O rings that are top quality along with Stainless Steel Bolts.
Remove your factory side freeze plugs; clean the bore with scotchbrite (make sure there is nothing in the bore that can cut the o-ring). Thread the bolt into the plug retainer 2 full turns and install the plug in the block. Torque to 20ftlb. The freeze plug should go in with hand pressure only.
