F00 isnt the significant part of the part number. This part of the number will not tell you anything terribly significant about the part. Nissan numbers read like this:Sample (NISSAN S14 MAFS): 22680-69F0022680 = This tells you what the part is, ALL Nissan MAFS will start off with this number.69F = This is the model/engine, so 69F means S14/S15 SR20DET, 52F means S13 SR20DET, you need to know this part of the number to know what car some part came off of.00 = slight variations in basically the same product. For instance 00 on an S14 MAFS means its from a Zenki S14 (1993-1995), if it says 01 its from a 1995-2002 S14/S15. The only difference is the shape of the connectors.rudee023 wrote:Part # F00 is a SOHC MAF. It's interchangeable with the SR MAF but is not a true SR MAF if you are anal about it.
