JEGS Universal Freeze Plug/Core Plug Block Heater

Product images may differ from actual product appearance.

JEGS Core Plug Block Heater is the essential item your engine is screaming for! Ideal for race cars! Preheating your engine's coolant and oil prevents wear and tear on vital engine components by radiating heat to surrounding components, such as engine bearings, valvetrain, intake manifold, transmission and starter, which will allow for easier cranking and engine starting. Brings the engine to operating temperature quicker by cutting down warm-up time, saving fuel and engine run time. We suggest using one heater per side on V8s for quicker heating results. Installs into a core plug hole in the block and comes complete with a 9' grounded power cord that threads onto the core plug.
