Hello… wanted to ask if it could be dangerous for the engine if you installed an open air filter. There are some providers. For example of sk-tuning with TÜV registration, k&n, green etc… I don’t know about these things. They seem to let more air through than a normal LF… can’t it happen that even small dirt particles slip through this filter and thus cause damage to the engine? Because, what brings me a good sound u and possibly a little more power (as always promised) when the engine gets stuck at some point… Greetings Björn
