Used OEM Nissan Mass Air Flow Meter for all '90+ Nissan 300zx models.

One of the many key sensors of the 300zx.  The MAF meter measures all air entering the engine at the air filter.  This information is interpreted by the engine's ECU which then adds the appropriate amount of fuel.  Over time, like any other sensor, the MAF can and will go bad.  This is a sensitive piece of electronic metering equipment that must be calibrated perfectly to ensure proper fuel economy and engine saftey.  Beware of aftermarket, remanufactured, or Chinese counterfeit units that are not calibrated properly.   Most used replacements have now exceeded 20 years in age and calibration problems are common resulting in lean air fuel ratios and blown engines.  As a result, Z1 recommends a new OEM MAF sensor that we offer at the best price anywhere. 

 Original Nissan OEM orange label N62, either a  4 pin or 5 Pin MAF sensor will work  for all 1990-1996 models.  The fifth pin is not neccessary and was removed on the newer models.  4 and 5 Pin untis are completely intechangeable.
