When i bought my new MAF this morning the parts guy i know and deal with told me that the computer says the MAF is actually an update by Nissan and has been tweaked in some way from the original MAF??? Is this true?

It also said somethin about replacing the air filter along with it but i have a PR CAI so i don't have to worry about that

 

yes they update the MAF. some people said it made the car more smother.

 

Does it include the one for 2k2-2k3? I just had mine replaced today.
