I heard a lot people say those Aftermarket Filter has a lot more dust going into engine than stock filters.
true or false ??
true, you will get more dirt into the motor. I've always put high flow filters on all my cars I change the oil more often since it will get dirty quicker.

Your main concern with particles getting past the filters should be cylinder wall damage. Frequent oil changes wont help that.

I've been through this high flow filter talk since i was 16. All my cars have had high flow filters none of them have had any issues, not a single one. I've had a few that have passed 200k no problems zero engine issues. If there is any damage I've never had an issue and I can only speak for myself.
Doesnt matter what you’ve been told @16 or what i say now, facts are facts. Take it how you like it.
i think by my last post your thinking I'm disagreeing with you and thats not at all my case. I do agree there is more dirt going in and aftermarket high flow filters don't filter as well so not disagreeing with you for me it hasn't been a major issue or an issue in the past were it's caused me trouble. Either way i get what your saying.
i felt no difference at all. Pretty much exactly what i was expecting. Tune is coming hopefully this thursday i know that ill feel a difference, lol.
For some reason, my friend said he felt a big difference on his cls63 AWD with the filter...... too bad i didn't have a chance to drive it before. He also got renntech tune and downpipe. Sounds amazing and power gain was obvious (as in just feeling when driving) just by comparing my e63 and his.

when it comes to power adders Ive never had vey high expectations at all. I did not notice any difference at all the car feels stout from the get go and im pretty sure it will hand my old e55 its you know what fairly easy. Even with this tune I'm expecting about 550-560whp if its anything higher i would be pleasantly suprised.

What you claim “facts” might not be true.
All my cars had similar filters for over 18 years and never had any problems
My project car been boosted for 7 years making over 800hp with said filters and haven’t had any issues and it gets abused more than any car you’ve seen.
If you’re worried about micro dust ruining your cylinder walls then you have bigger issues my friend.
The UPD filters are thinner than the BMC filters (we tested them all on the dyno ) for even less flow blockage. Add the filters and spacer kit and 100% open inlet flow. Good aftermarket filters do a very good job at keeping dirt out of the engine. They are reusable, so just keep them clean and engines keep running with more power. I have run aftermarket filters in everything I have ever owned. Those OEM paper filters do not wick away water well and water really can kill an engine.

First read what i said smart boy, “Your main concern with particles getting past the filters should be cylinder wall damage. Frequent oil changes wont help that.”
thats the fact im reffering to, if you want run straight no filter lol i never said high flow filters will ruin your engine, i said if particles do make it past the filter an oil change wont help. Damn i gotta dumb it way down.
ps: if youre ever in seattle hit me up ill take you for a ride and show you how to push a car lol and youll learn a thing or two.
This was probably not a widespread issue but as some of you might see, just because it didnt happen to you doesnt mean its impossible. So ride away while reading.

Lol kids get butt hurt easily nowadays..
Poor thing. I’ll pass on learning anything from someone so immature.

LOL thats what i thought oldfart. Now leave the internet for people that know how to scroll and read. But hey if you ever change your mind my offer still stands, have a good day.
Facts.
1. Higher flow does let in more dirt/dust. You can see this in the fact that downside of your filter,.. there will be more dust in the intake. less Air restriction, more stuff gets in. Don't have to be an engineer.
2. In a daily driver, you won't get much appreciable harm from this dust. How long does it take you to change your filter?... 10k?... 20K?... 40k?
Where a low-restriction filter is going to harm you is in high dust conditions such as off-roading... primarily desert off-roading (your Bajas etc). I've run into this on my off-road trucks and wound up going back to heavier filters due to the crap downstream of my filters but,.. regular, going around in the woods type stuff... while still dirty, didn't cause any undue alarm.
There is a particular study performed years ago that I'm trying to find again.. it was a construction company in the desert (Middle East I believe) that tried going to K&N filters. They performed engine tear-downs every like 12 hours, I think.. which is normal for multi-million dollar construction engines, from what I remember, and they found HUGE amounts of sand/debris getting into the engines with the K&Ns and so went back to the stock filters.
I'll look for that study when I get home but not gonna kill myself doing it, lol. Like I said,.. it was years ago.. but the best empirical data I can think of.
I've run aftermarket filters for almost every car I'v ever owned with no documented engine damage. Sure, it may let in additional particles or dirt but I haven't seen any side effects or engine damage. Thus, just from my experience, I'll continue to use aftermarket filters until the day one of my engine explodes...assuming that it can be diagnosed properly that the explosion was a direct result of the aftermarket air filters.
People of the Internet age often confuse anecdotal experience with scientific, statistically significantly data garnered from a true scientific study, one based in and rooted in the scientific method.
i will never use BMC or any other aftermarket filter because i actually agree with Tim, but I admit I agree with him because these anecdotal internet reports are compelling enough to me AND the gains are so tiny ... that it's not work the risk; but I promise you I don't have a computation of successful filters vs failed filters sold by BMC to support scientific standards of inquiry
