K & N filters

Ok, I'll try one more time to explain friction, scoring and what high silicon rates can do to the inside of an engine.

No need, I completely understand all that. No need to be condescending either. I have a full and complete understanding of how an ICE works. What I do question is getting high amounts of silicon in an engine in city driving. Air flow testing of air filters doesn't test real world events. Oil analysis after driving in real world conditions is the only way to properly test. Unless it is shown that a significant amount of harmful material collects in the oil of an engine with one air filter used over another everything is just speculation. A SWAG if you will. But, that is more involved that a simple dirt flow test.

Additionally, I am not stating that allowing a higher rate of passed "dirt" won't cause engine damage. However, unless someone tests it all you have is theory. And theory doesn't always match reality.

Off road driving is a completely different environment, much as on the water is a completely different environment.

So, unless you have links to someone doing engine analysis after using different air filters under "normal" (non-off road) conditions then we don't have a real answer.

However, feel free to continue to treat me like a child that needs to have all this explained instead.
