Anyone ever remove MAF screen? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Their is a screen in the Mass air flow sensor.  I know that in many v8s etc that you can remove the screen, and mildly port the Maf sensor itself.  The screen is normally used to "straighten" the airflow, and give a correct reading, but it is also a hinderance in flow.  By removing it in muscle cars, you can lean out the A/F mixture artificially by having the PCM think it is getting less air than it actually is.  Can you do the same on a 240sx?  

Any other free mods to a stock 240sx?
