Mass air upgrade

Mass air upgrade
Hello, I have an '02 GMC Sierra with a 5.3.
I noticed that the mass air sensor looks more like a mass air restrictor. I've seen an after market sensor that'* much more open to allow better airflow. Has anyone had any experience with an aftermarket mass air sensor?

Only if you are upgrading by means of a turbo or supercharger. Otherwise, leave the stock one alone.
