This is a Cylinder Cozy from GMK Supply. This Cylinder Cozy wraps around your new engines cooling head and are used to raise temperature during the break in process. This sleeve will not only help increase the temperatures during the all important rich break in process (low temps during break in prematurely wear the piston/sleeve), but they also protect the engine head, unlike using aluminum foil. Get your engine fully broken in and looking like new when you are done!
