It has been said that stock runs best. Simply put, low grade aftermarket parts are no particular bargain if they don’t perform properly or possess the same degree of longevity that original equipment manufacturer (OEM) parts provide. When it comes to your livelihood, as it pertains to your turbochargers, insist on OEM replacement parts purchased through a reputable source.
Most modern diesel engines are turbocharged. A turbocharger allows the engine’s horsepower and torque to be multiplied through forced air induction. Inside the turbocharger housing is both a turbine and an air pump. Both are driven using the same shaft. Spent exhaust gases, escaping the compression chamber, are used to drive a turbine at very high RPM. As the exhaust turns the turbine, the air pump impeller draws high-volume, low-pressure ambient air into the engine. The ambient air is drawn in through the front air-dam and the intercooler, in order to ensure that a steady source of cooler, denser air is available to the air pump. This additional air induction allows the engine to burn an increased amount of fuel, resulting in more horsepower and torque.
Why buy OEM Turbochargers?
Aftermarket turbochargers aren’t manufactured to the same stringent specifications as OEM one, neither are they made from the same top-quality steel and components. Turbochargers are by nature very powerful, yet they operate under very delicate circumstances. The turbine wheel and housing must be meticulously machined and assembled; tolerances between the impeller and housing can be well under several thousandths of an inch. Extreme temperatures from the exhaust, which drives the air pump, coupled with these very close tolerances demand that the turbocharger be designed, engineered, and manufactured to the most rigid guidelines. You just don’t get that type of quality anywhere but OEM for turbochargers.
