i havea 2000 s4 and i was putting in an s-flow filter with a darintake and i think silicon got onto the maf sensor screen (very small pices)and sucked into the system. i now hear a what sounds like an (injector knock)at idle. i dont feel or here any performance loss when getting on it nor do i hear the benifits from putting it in. will the silicon burn up or go away if any thing is stuck or do you think any other problems could occur . thanks
