Part of the problem is in the four letter word you used to describe the filter. I am on Dub, Ford and Honda forums and nobody seems to have much good to say about that filter brand.
Could it be expansion and contraction of heating and cooling metals ... that would be what I think it is. But try it with a OEM filter, I use Mobil1's and K&N's the most and have never had the problem with my 1.8T but we don't get too cold here, so I can't give more than that.
