well..i follow the 5k kms change everything naman...so no problem. i dont think the extra dirt could have affected my cars.

kahit naman oem filter, may dirt paring pumapasok.

From what I read it would be a trade-off, either have more airflow/dust or less airflow/dust.

The most noticeable change in aftermarket filters is the engine sound. Also, K&N's sucking of air is better than Simota. I've tried both and I can really observe the difference. K&N responds better the moment I blip the gas pedal.

Your engine breathes better with aftermarket filters. Yeah, it could be true that more dirt enters the manifold, but even with stock filters, there's always a way for all those particles to penetrate. You will just have to change oil a little bit more often.

You could try what we used to do... naked velocity stacks on twin carbs... now that's dirty air. Of course, we put mesh material on top to keep pebbles out, and we had to change the oil a bit more often...

The extra dust and particles that the K&N lets in are minimal, and normally inconsequential, unless you have a sensitive MAF.

Aftermarket free flowing filters can theoretically let more dirt in. Not just because the filter media is more free flowing but also because using open-type filters disables the anti-dust systems of OEM intakes. Mitsubishi uses a dust pan on the Pajero, Nissan uses a pre-filter on the Patrol, Toyota makes use of the cyclone effect on the Land Cruiser. Some cars also have these built-in systems.
