this.

It's attached to either the tube or the airbox. both present a known restriction and the system is calibrated to this flow and relative turbulence.

If you change this too much you will need to recalibrate the MAF somehow.

Float a msg over to Overkill and you'll hear the same thing. he recommends some tubing between the filter and MAF for this reason. Tosses off the calibration.
