- In conclusion, the MK7 GTI spark plugs are more than just a small part in a larger machine; they are integral to the car's performance, efficiency, and longevity. Understanding their function and significance can help GTI enthusiasts appreciate the intricate engineering behind their beloved vehicle and ensure it continues to deliver the thrilling driving experience it's known for. So, when you hear the roar of that TSI engine, remember the tiny but mighty spark plugs that ignite the fire.
a)
Modern engine oils, such as the current SG classification for gasoline engines, contain a large fraction of additives, many of which are detrimental to fluoroelastomers. The primary functions of oil-additive packages are to protect metal parts, avoid deposits in the engine, minimize oil degradation, and adjust fluid viscosity. Little attention has been paid to avoiding damage to rubber seals. Instead, elastomer producers have been expected to provide new, higher-performing products at no increased cost to auto manufacturers. Among the additives with moieties that may attack fluoroelastomers at high temperature are detergents (phenolates), dispersants (succinimides, alkylphenol amines), and antioxidants (amines, sulfides, hindered phenols).4 Many of these components are multifunctional, containing phenol or amine groups that can dehydrofluorinate and crosslink VDF-containing fluoroelastomers, leading to loss of elongation and eventual embrittlement. However, the rate and extent of reactions with seals are affected by many factors, including whether air is present in the system. When oil is exposed to air at high temperature, additives may undergo considerable changes. For example, a significant fraction of amines may be oxidized to amides, which have little effect on fluoroelastomers.5

However, it’s plagued with a few drawbacks, such as poor resistance to ozone, sunlight, and weather. It also has limited resistance to high temperatures and flames.
Conventional oil is the most commonly used type of oil. It is ideal for light-duty, late-model cars with low to average mileage and a simple engine design.
If you follow the above instructions, the oil seals should work properly. Also watch the video below for an example of the installation process.


Carefully lift off the cover. If it sticks, gently tap it sideways with a soft-faced rawhide or nylon hammer, or with the heel of your hand.
2) Rubber material
Several variables, including maximum temperatures, required lubricants, available space, and more, may influence your choice of bearing seal. Each factor can affect the type of bearing best for your application, the amount of material required, and other factors. Although the choice of seals is crucial to the effectiveness of your bearings, you don’t have to make that choice alone. Our experts at NBC bearings can collaborate with you to identify the bearings and bearing seals that provide the best, most affordable solution for your application, environment, and finished product.
