how does these compare to OEM?

 

+2 wheel hp over stock.

 

nothing you will ever notice...

 

But could be enough to make a difference if you lined up next to a car that does not have one.

 

Why do you refer to this price as a "blowout" sale?

This filter is normally sold elsewhere for under $ 90 .

 

Do you have a link?

 

Why, do you want to buy one? Lol

Mike, I looked at an (older year ) 911 BMC filter price, not the 996 .
I apologize for the mix up.

But I did buy one for my 997 S from Powertech in N.J. for $100 a while ago.

I removed it a few weeks later, after I got a lecture from my Cousin (who is an Engineer and VP with MB ) on what the long term effects of these "high performance " filters could be.

According to him , oiled filters are at best ~30% efficient ( 3 micron and larger ) when new and get worse the more dirt gets impinged on the oiled surfaces.
The rest goes past the filter .
Some winds up on the cylinder walls , where ,together with the oil it makes a
great polishing compound and most will go out the exhaust , but some will accumulate in the engine .Especially the smallest particles which (among other things) form sludge deposits which can eventually break loose and prevent proper oiling some vital part . When that occurs, bad things happen very fast ( I know first hand )

To K&N's credit, they do warn potential users not to use these filters during colder weather (because the oil viscosity changes) and when it's raining outside ( I assume because microscopic water particles with dirt in them do not stick to oiled surfaces very well )
They are OK for an occasional afternoon at the track,but i would not use one in a daily driver for those reasons.

I do not remember reading a similar warning from BMC .

By contast, a regular filter starts at 85 to 90% efficiency and gets BETTER the dirtier it gets.


By (unfortunate) coincidence, my wife's Audi ( A-4) died of a heart attack a few weeks later, just ~ 15,000 miles past warranty,due to engine sludge.
I just had an oil change done at the dealer the day before and Toyota had just settled a class action law suit for the same problem around that time .
In fact , it was probably the oil change ( synthetic oil ) which loosened the sludge ,which wound up clogging something in the engine .

This circumstance and that the car was always properly maintained at the dealer,I believe probably were the main reasons why Audi replaced the out of warranty engine at no cost without the slightest hassle and I respect them for it
(would have been ~$12,000 otherwise)

And the Audi had a regular filter in it .From what I saw inside the engine, I doubt it would have made it to 65 k with an oiled filter . Lol

I have this information from a very credible source and I have personal
first hand experience with engine sludge .
If you have better information on the use of these filters, please inform us.

Thanks , and again, my apology for the pricing error.

 

Nice info JCS...while I love modding as much as the next guy, I usually leave the powertrain alone. Why? There is always a tradeoff...you dont get anything for free. Yes it may get you a few more HP, but at the risk of letting more dirt into the engine....I have had great luck so far with longevity of cars...its good to see pros and cons here...I did think the BMC filters were dry...am I wrong? I thought they were better and different from the K&N, especially for P cars...

 

I think BMC makes both types .Wet and dry
I was speaking of the oiled ( wet ) type

Since both BMC and K&N claim " high efficiency " ( low pressure drop thru filter ) they can't be too different , but the BMC is more expensive
(and one is made in Italy and the other one maybe in China ? Lol )

 

That's what I thought. You scared me there for a second.

Can you explain as to how?


There was a service bulletin that went out stating that 1.8T VW/Audi owners should begin to use synthetic oil and a much larger oil filter.

This was an oil feed issue, and the fact that the car was designed to hold less oil than it really need. Plus the oil changer intervals recommended from the factory were WAY to far apart.

I know many Audi owners that had failures right after the warranty ended.

That issue has turned many off from buying another Audi.

My point is though, these failures were happening on cars with stock filters. Not aftermarket filters...

Bottom line, I will be honest and say that I have ZERO scientific evidence on the filtering ability of the stock or aftermarket filters.

The only thing I do have is experience.

I've been working here for seven years, and was getting my car worked on here 3 years before that.

I have countless friends and acquaintances with modified cars. Some with low miles some with high miles.

Personally, I had a BMW that had a K&N since new and the car was sold with 330K miles on the clock.

Plus, I have yet to see all of these supposed MAF failures from over oiling. And we see different cars everyday!

What we do so is weak Bosch MAF sensors that fail regardless of what filter is in there.

I am going to let the public decide. If you take a look around our web site, we don't sell fluff. If it does not provide a tangible result, we will not sell.

If we felt in any way it was going to harmful to your car, we would not sell.

I appreciate you reading this.

If you have any further questions, please just ask.

 

Hi, Mike,

I will try to answer your main points as best I can .

To item 1:
An oiled filter works on the impingement principle .In other words, dirt particles in the incoming air get "stuck" on the oil coating . As the dirt particles start to coat the surface of the filter ,less and less dirt can stick to the surfaces and the efficiency gets worse the dirtier the filter gets.
(Efficiency being the percentage of dirt particles being retained by the filter . A 30% efficient filter will retain 30% of dust particles 3 microns or larger , 70% goes past the filter )

A regular filter on the other hand consists of interlocked or woven fibers and the dirt particles get stuck in the passages between them .
The more dirt in the filter , the smaller the air passages become and the filter becomes even more efficient .
( naturally , there comes a point where it needs to be replaced tue to the pressure drop thru the filter )

To item 2 :
The Audi in question used only Sythetic oil , from day one.

To item 3:
My point is that if the Audi had used an oiled filter, the sludge build-up may have been even sooner and more severe , due to more dirt getting into the engine.

To item 4 :
I am a Mechanical Engineer with many years experience designing industrial clean rooms , automotive engine research facilities ( dynamometers etc.)and I am pretty familiar with all types of filters, if mostly of the industrial application type. But the principles are the same .

To item 5:
It would be interesting to see what the insides of the engines look like after ~ 50 k miles in cars using oiled vs. standard filters.

To item 6 :
I do not recall if BMC includes warnings with their filters . But , to give credit to K&N ,they do .And since their filters work along the same principles, I see no reason why they should not apply to both.

K&N clearly states that their filters are NOT TO BE USED at lower outdoor temperatures ( presumably because the viscosity of the oil gets so low that dirt no longer sticks to it ) and NOT TO BE USED during wet weather ( i.e. when it's raining out . Micron size air/ water particles ,which also contain dirt, will simply roll off the oiled surfaces of the filter and pass right thru into the engine)

Given the warnings from K&N , it is pretty obvious that these filters were never intended for daily drivers.
What I do not understand is that otherwise rational people ignore them, just for the sake of a few ( and I mean A FEW ) extra hp , unless they really don't care because they get rid of their cars long before any problems can occur .

I have no stake in any of this. I just wanted to point out some of the problems which COULD happen when people use products without being fully informed of their potential pitfalls .
So take it for what it's worth .
