Hey, so, after careful consideration and recommendation of a not unknown forum member (thanks to Markus!) I decided for the ITG plate filter. It makes a good impression at first glance. Foam rubber plate with a very tough oil liquid and absolute fit accuracy. Now you can of course not expect from a change plate filter the world, but the intake noise is clearly louder and the engine is a bit more revolving (subjective impression regarding turn Fryer). All in all, I have the impression that the whole engine has become a bit louder. However, I cannot (yet) notice the louder exhaust noise as with NOS. The part costs incl. shipping and NN 62 EURO and is imported by ISA-Racing from England. Waiting time about 4 weeks, which is worth it.
