Could not find a decent post containing all the information needed, so I thought I would compile one for the text.
Start by ordering one of the Beetle Engine covers PN# 07k103925 from the dealer or a Vortex supporting vendor
Remove the old cover. (See air filter DIY for info)
Take a T-30 bit and remove the studs from the rear (circled). They will be replaced with the two screws you will remove from the center of the motor.
Before swapping them, Split a 6mm lock washer so it will just clip onto the stud, above the captive rubber and steel washer.
Swap out the bolts from the center of the motor to the back where you removed the studs, Torque to 10 nm.
Reinstall the two studs with the new washers on them to the center of the motor.
Now that the studs are re-positioned, we need to swap one of the rubber mounting bushings from the old Jetta engine cover to the new Beetle cover.
Looking at the back of the beetle cover, you will need to replace the upper left short bushing with the one from the same position on the Jetta cover.
Small Beetle one with larger Jetta one:
Installed on cover:
The bushing fits fairly well in the holder, but you may want to add some glue or something to hold it tight. (I did not )
And now the cover will bite on all four studs. Giving you a solid fit!
Now to remove it and start the rest of the painting process!
