Hello, id like to get the side vents on the XJ done in black. Im considering wrapping them or painting. However they need to be removed as well as painting the bottom grills. It looks like the main grill is easy to do.
Is there any instructions on how to remove those?

 

From the pictures of the side vent the removal looks a little tricky. It looks like the vent needs to be pushed forward or backwards you may also have to pull out on it.
It is not held on by adhesive and you do not access the fender from the back side to remove it.
Go to Ebay and at the search type in Jaguar Side Vent. You will see the vent and a picture of the back side of the vent that will give you an idea of how the vent is mounted. From that picture you should get and idea of its removal.

Good Luck....
