The temperature in the engine compartment cars of the past, slightly above the ambient temperature. Around the engine there was enough space to easily carry out any maintenance operations, and spark plugs can be replaced without disassembling anything related. With the increasing complexity of designs, increasing density of components and assemblies, temperature of engine compartment increases constantly.
Modern cars have a compact engine compartments are much less air circulation and increased heating of the engine attachments. All of these factors are due to efficiency, environmental friendliness, striving to make cars more convenient and efficient, which leads us to the emergence of a new phenomenon - corrosive environment under the hood. "Workplace" for the components of the power unit is becoming more and more harsh and hostile.
The materials used in the manufacture of parts, not always kept pace with the progress of the requirements that they imposed, and this leads to a reduced reliability.
Replacing rubber or ethylene-propylene rubber (EPDM) tubes and hoses for silicone, You will receive superior resistance to temperature effects as heating and cooling, high pressures and vacuum.
Even in Motorsport the installation of the silicone tubes and hoses is not considered as part of tuning or improvement is a basic element, without which it is impossible to create a reliable and efficient powertrain.
Pipes and hoses are not included in the list of items subject to regular replacement, and are dismantled only in case of failure, when failure has already occurred and the node has failed. That is why they are subject to careful regular inspection and preventive replacement at the slightest sign of wear or increase the load on the power unit.
Silicone items, in contrast to rubber, not afraid of high t low temperatures, high pressures and is not prone to cracking and loss of seal.
