Advertising.
In the last post you said " ...performance filter of course filter the air less..." and I said "...they don't tell you that..." and now you say it does.

Which is it? You can't have both.

Well jay.
I also know - mostly from forums, never seen an official report about it or any sand or dust in the engine before -as performance air filters filter less but they advertise this way , +99%, which is contrary to the belief and what you said.
So, to know the real truth, is there anything solid -not like something you heard in a forum - you can share with us to support your idea?
This way, we can find the truth.
dont get me wrong, it is not like for who is wrong who is right, just to know the facts about performance filters.
Maybe dna is lying who knows.
