Guys, the screen is there for a reason. Your sample tube needs the air straightening so that the sensor wire gets an accurate reading. People used to do this on camaros and trans ams all the time and they'd start to ping. You might not hear it over the sweet sound of SC. Aftermarket sensors don't have the screen because the sample tube is designed differently.
