Boyesen SuperCooler Kit Black for KTM, Husqvarna and GasGas – WPK-42B

Internal engine heat, although needed for horsepower, is also extremely destructive to your engine if it is not managed properly. Internal engine heat, although needed for horsepower, is also extremely destructive to your engine if it is not managed properly. Internal-combustion engines burn fuel hotter than the melting temperature of engine materials. When an engine is operating out-of-balance with its cooling system's capacity, the internal temperatures often rise to levels that cause damage to the cylinder, piston, and valve-train components. If these parts become heated over the optimal operating upper limit range, component damage will begin to occur. Reduced to its common reasons for being essential in an internal combustion engine, cooling system efficiency can have a dramatic influence on the longevity of the internal working components of your bike's engine. These include the reduction of thermal stresses and strains caused by pre-ignition and detonation (particularly the latter), distorted cylinder bores, potential damage to pistons and rings, and damaged valve-train components.
