Most competitors commonly cut the size of the engine and transmission coolers as well as the cooler material to reduce costs. This is dangerous as it can cause premature damage to the engine, transmission and other components. OSC uses copper/brass or stainless steel engine and transmission coolers wherever it came original equipment. We do not substitute with aluminum to cut costs.
