Remmele style side air scoops?

[Racelook]

I have bought mine (Remmele look-a-like airintakes) at Frankys VW Service in Holland..

This is what is told to me how i have to install them.
-At first you have to cut the hole for the intake
-Then you reces an edge to the inside of the car.. (the hole around)
-Then you gluy the intake against the recessed edge with windowgluy (proffesional gluy that they use when they gluy in new windows in de modern cars)
-Then you start laying fiberglass-plates from the recessed edge towards the intake,, so at the end the airintake is totally sealed to the body..

Mine airintake is hopefylly going in in about 2 / 3 months
