Changing the air filter today and noticed large cracks in the filter housing where it is closest to the exhaust manifold. These cracks are behind the air filter and bits of plastic are about to break off which would allow unfiltered air to be drawn into the engine. I've taped over the damage both inside and out with electrician's tape but am worried this won't stand the heat from the exhaust. New boxes seem to be like hens' teeth but if anyone can point to a source or offer advice on a repair to the existing box it would be much appreciated. I imagine this kind of plastic degradation would be common on any older Stilo 1.4.
