Don't put words in my mouth. I was voting for the OP to buy K&N. I never said I was buying. I am too much of a man to want to spend any time at all douching the filter every so often.wait... GN is saying that BMW didn't design something perfectly to last the life of the car straight from the factory

He wasn't contending that a K&N (or any filter for that matter) would cause the engine to blow up. What he said was that used oil analysis have shown higher levels of silicon (ie; dirt) in general with those using K&N air filters. And that higher levels of dirt is not good for the engine.
rolleyes would, but given a short period of time like a couple oil change intervals and there will be measurable wear.Given the persistent report of people using k&n for years and years, there hasn't been a single case of engine blowing up in the short term, or in the long term. All this dirt mongering is unjustified, and does nothing but serve to hype up business for little shops that like to say nice.He wasn't contending that a K&N (or any filter for that matter) would cause the engine to blow up.

Think of it this way, add 100ppm (not much really) of silicon in the particulate range of 10~25 Nmm (which a K&N filter WILL let in, BTW), and mix it with the oil film on the cylinder walls. Drive normally and let this abrasive paste work it's wonders on the cylinder walls and piston rings for awhile. I bet we see those same folks coming back in here whining about why their cars are now consuming large amounts of oil. Won't happen overnight like "blowing up the engine"
You really need to present a better argument than an engine "blowing up". No one is saying that and frankly, the only way to do that to your standard would be with some sort of explosive
. More dirt (and I just threw out that figure to show more than normal amounts) will indeed cause more wear. It does not "blow up" the engine as you would like to overdramatize, but will lead to other maladies such as increased oil consumption. Kinda like YOUR car does.Don't really feel the need to clarify this for you, but I will. The "Bob" in Bobistheoilguy is Bob Winters. He is a real person and started the site along with some other very educated tribologists and chemists. Bob suffered some medical problems for awhile and gave up the site to a new owner. Most of the "brains" are still there to some respect, so the level of knowledge there is pretty much intact (unlike your level of knowledge). Bob is back on BITOG and also belongs to other related sites.
Sure, keep telling yourself that. It's a pretty basic theory really, one that even YOU can grasp. More wear inducing particles (dirt for example)= more wear. Simple. And is what most oil companies and engine designers try to fight against. There is no magical limit, ALL wear inducing compounds are considered bad.
Whenever I've run into friendly little debates like this, OP, I just go stock...and we have friendly debates like this on everything...wipers, every fluid anywhere near our car, color of every fn thing on car, even what metal you want your bolts made out of...every fn everything...just go stock and you'll eventually end up with as good a car as you bought.
My oil consumption has nothing to do with k&n since the car never had such a filter installed. So your claim of connection between k&n and consumption is just a random shot in the dark. Regretably, you cannot expect people to be convinced.You really need to present a better argument than an engine "blowing up".

So where did internet bob get his ideas from ? Which engine or oil company did he work for that gave him the semblence of authority on oil ?
Engine and oil companies have succeeded in their fight. This is why we are seeing ever increasing oil service intervals. Most k&n users more than likely change their oil significantly more frequently than manufactuer recommendations. Therefore, any increase in particle intake is tempered by more frequent removal. So the overal effect is neglegible. Further more, there's no evidence to show the size of particles allowed through by the filter is capable of wearing out the engine within its useful lifetime.
I lack such receipts. That's more than the proof you seek.
I heard 6-10" that sucks! Be careful driving!
If you're using the stock airbox, going aftermarket won't make your E46 noticeably faster; best option considering price/filtration/ease/MAF safe is to use the OEM filter brands like Mann. If you seek a perf boost, you will need a new intake design.
I think I contributed...unfortunately, part of what I said was serious and I even pretty much made it clear which part that was! :lmao:Doug, don't forget to read GN's thread about how to drive (and buy tires for) winter driving
I have never seen any proof that k&n caused an engine to blow. This is the proof we are looking for. Any other proof is irrelevant. So what if there's more silicon in the oil ? If silcon doesn't blow up engines, we don't actually care.
