Duramax LML Humidity Sensor Block Off Plate For Intake 2011/2012

Did you purchase an intake or turbo kit for your 2011 or 2012 Duramax LML that has the second sensor port in the intake tube that is used for 2013-2016 LML's? This little plate will block off that second port that you do not have a sensor for. The 2011/2012 Duramax only uses a single MAF sensor in the intake tube where the 13-16 Duramax LML trucks have a MAF sensor and humidity sensor in the intake.

**If you own a 2013-2016 LML, this sensor should not be removed from the intake system**
