OEM parts are not the cheapiest parts you can find. However, we can say you get what you pay for. Theres is an inherent pressure n owners and managers to see the reduction of their operational costs, so that pressure often leads to corners being cut. The first corner that gets cut is replacing broken parts with generics rather than OEM parts. Though going OEM can be a bit more expensive up front, it brings value to the table in terms of reducing liability and by alleviating future risk of failure. OEM parts are guaranteed and must go through quality control checks to ensure proper functionality.
