Will say it once more, the MAF can be descreened. However, as with any engine mod, it's advised to have the equipment (tuning software) so that the change can be properly adjusted for in the tune. It's best to adjust the MAF table after removing the screen, but not always absolutely necessary. The car will idle leaner which may or may not cause issues.

I have never had an issue w/ a descreened MAF that couldn't be adjusted for in the MAF table.

It isn't to be removed by backyard mechanics looking to gain more horsepower. You might enjoy some extra horsepower while airflow is misdirected around the sensor and your car goes lean...which then could proceed to blow your **** up.

Leave the screen alone.
