Pjinca, most, if not all of the so-called engineers' errors were actually the accountants' fault! They didn't authorize the engineers' choices.
We aren't saying that there is evidence of engine harm due to K&N filters, but that there is NO benefit in using them, but the theoretical possibility of damage, especially if one is not changing one's oil frequently.
And please, let's not get into the 'mine is bigger than yours, therefore I am right' nonsense.
Respectfully, Bob P.

Paran, I (for one) did not question your intelligence, I questioned the science of the study presented and for evidence of cars damaged directly attributed to the K&N (or similar quality/type of air filter). Nor do I agree that the N62 is a flawless piece of engineering - ask anyone that has had a totally stock 545/550 when at about 100k miles the carbon build up completely clogs the exhaust ports leading to the head needing to be removed and the carbon removed with what amounts to a Dremel. The engine is magnificent, but it is not without flaws. That said, I look forward to many many years with mine.

haha, I'm going to have fun with you.

I inserted the above, as I'm quite confident you are unaware of what "anecdotal" means.

No, but you don't have any studies that show it doesn't damage your engine, save for your anecdotal evidence as I illustrated above. (See, I can play this stupid little game of yours as well) There is review after review as well as the studies that Paran posted that say "yeup it lets in more air, but it lets in more dirt too." It is common knowledge that dirt inside your engine is a bad thing. No one has said or promulgated that a K&N is like pouring in the Atacama, all we have been asserting is that it surely isn't good for the motor, its n/a HP gains are non-existant and no one keeps these cars long enough to justify their price over OEM ergo, you are just like the people who purchase the $20 muffles on eBay for their $1,000 Sentras. Congratulations.

First, unless you can back this up, its a garbage argument, and you are doing exactly what you are accusing us of -- that is pulling info out of your ass. But I digress, you cannot prove it, nor can you justify discrediting the source. Seems to me like you are pulling justifications out of thin air to justify your way of thinking. That's fine -- most uneducated people do so -- just man up to it. .

Dude, you should have just quit here. "Alleged" is probably extending your vocabulary just a tad, but unless its designed to be in the engine i.e., fuel, air, exhaust, and the "grime" left over from the combustion process it is a "contaminant". But then again, this is all just a vast scheme of all the paper air filter manufacturers the world over to disprove K&N, even though they already supply the overwhelmingly majority of air filters the world over (via OEM contracts).
----
Please. In fact, I want you to list in detail all the problems with the e60, with all the engine and transmission configurations backwards alphabetically in pig latin.

Sure. BMW has to put a package together that not only meets a certain cost structure, but also has to last for a certain amount of time. Their goal isn't to get every single square ounce of horse power out of theirs cars, as that will very likely limit the longevity of their components, and thus the car. Ergo, they look for a happy medium of performance and longevity. This clearly means one can add onto the car and increase its output, and if properly maintained its longevity won't be affected. The problem is most Americans don't properly maintain their cars, and thus an unmaintained car that has been driven hard for 70k or so -- its practical life as a reliable DD is pretty much over. I expect some stupid retort of "herp derp I maintain my cars" which is fantastic for you. The sad thing is -- most people don't.
Yeup, I am entitled to mine as you are entitled to yours, but as far as the evidence goes, I've yet to see any save some anecdotal evidence and a whole lot of whining.
So at this point, the ball is in your court hombre. Either cough up some evidence supporting your thesis (the K&N isn't an egregious waste of money for an N/A car such as yours) - or admit that ... how did you so eloquently put it ... that you have a small brain and even smaller genitalia.
EDIT -
Most of my derp wasn't even directed at you, I just called you out for backing up an argument with anecdotal evidence.

As I said, I have used K&N for over 10 years in a variety of cars, none of which had an single engine problem.

High Pressure Fuel Pumps in 535's
Useless Charcoal filter in US cars in the intake that only serves to restrict airflow
Faulty passenger air bag seat sensors
Faulty window regulators
Squealing brakes
Brake booster pump (V8 Engines)
Intake coolant pipe (V8 engines)
Plastic coolant expansion tanks that crack
Transmissions that slam when they shift
Need I go on?

Folks, the OP asked this simple question:
Hi all,
I wonder if I can used the K&N performance lifetime filter for my 2010 BMW 535i ? My car still under MFG warranty. Air filter and Cabin filter are under BMW No-cost maintenance service program or not?
His inquiry was simply could he use it, as the air and cabin filters are under the BMW No-cost maintenance warranty program. Period. How this thread devolved into the merits of such is dubious - that was not his inquiry and only serves to muddy future searches.
So here we go: Is it OK to use it?
1) Yes - use will not void your car's warranty
2) There are downsides as debated above - increased particulates into the intake tract, yet not enough to adversely cause any proven or significant engine damage.
3) It requires maintenance, but said maintenance comes at intervals far exceeding those of paper filters.
So yes, you can use it without dealership inquiries or warranty problems. I have personally been using mine for 170k of my V8's 190k+ miles without issue. Yor mileage may vary. Good luck!

WOW this took my whole lunch hour! lol. This reminds me of the Fog Light Thread.
Any who, I just ordered a K&N although seeing all the mixed reviews online. I think i shouldn't have a problem.
