With the Mann air filter all I ever saw on the INWARD side was dust and bug remains. But the filter is there to stop that going further and so when the filter gets a bit old it drops into the box on the INWARD side from the suction hood.

That is a far cry from saying that any filter (OEM or K&N) allows it through to the turbos. I respect what you are saying greatly, but I'd need evidence to be convinced. It's somewhat like the diesel timing chain failures ... Lots of talk but no evidence as to whether it is crap oil; stop-start; manuals vs SSG and so on.

You're still No. 1 advisor in my eyes ... But evidence is what we all need.
