Left Exhaust Manifold - 1991 300ZX

For the 1991 Nissan 300ZX equipped with the VG30DETT engine, the left exhaust manifold is a critical component that can affect performance. Common OEM part numbers include 14001-30P00 and 14001-30P01. When sourcing a replacement, consider the 1990-1996 Nissan 300ZX models for interchangeability. Inspect for cracks or corrosion, as these can significantly reduce exhaust flow and power. Installation typically requires removing the turbocharger for access, so ensure you have the necessary gaskets and hardware. Regular inspection of the manifold can help prevent overheating and exhaust leaks, which are common failures in older vehicles. Always verify the condition of the mounting brackets, as they may differ between model years.
