Finally a vent that fixes the weak torn factory knee vent on your 2019-2021 Gen 4. It is made of tough aluminum with a super strong coated mesh covering with an extra layer of OEM spec waterproof material between the aluminum and the mesh covering to keep the fine powder out but still let a lot of air in. These vents are a solid aluminum. Nothing will ever tear through, and they actually add structural strength.
This vent simply rivets on over your factory vent. Includes rivets for easy install.
