The advantage of genuine Nissan engine parts is that they can be installed directly without additional adjustments, avoiding compatibility issues caused by non-standard parts. For example, the Nissan Fuga's transmission gearbox requires a specific torque output range; using aftermarket parts may cause shift jerking due to gear ratio discrepancies. Infiniti models' power steering pumps are sensitive to hydraulic fluid viscosity; genuine parts will clearly indicate the applicable fluid type.
During installation, it is essential to follow operating procedures. For instance, the transmission fluid must be completely drained before replacement; air must be prevented from entering the power steering hydraulic lines; and the refrigerant pressure of the air pump must be checked to ensure it meets standards.
