Those of you that have installed a 606 air cleaner on your twin cam HD, did you use the foam gasket that it says to apply to the front side of the filter before attaching your face plate? I have the contrast finned polished round cover and using a new filter. However, I don't have one of the gaskets. I will order a couple of them, but just wondering what it would hurt to not use it. Like I said the flat surface of the cover fits very flush when installed and tightened.
