According to our competitor's website, the WORKS unit only costs about 23% more--25% more surface area for 23% more cost.... sounds fair to me On to your other points:

1) A partial answer: https://www.evolutionm.net/forums/sh...9&postcount=37 There are other attributes that make the WORKS filter superior, but I think this is the one that most seemed interested in. Also, see posts #8 and #12: https://www.evolutionm.net/forums/sh...d.php?t=188794

2) They will filter with small amounts of the oil. They will also filter with no oil, but may not catch the smallest of particles and the filter becomes disposable at that point. WORKS minimizes the amount of oil placed on the filter.

K&N has a state of the art MAF testing lab. I was there with a WORKS Engineer spraying filter oil from an airbrush - enough to coat a hundred filters - directly onto a factory MAF sensor with no ill effects. We repeated the same, this time scooping huge amounts of dirt into the MAF.

Needless to say, the MAF contamination issue is a nice wive's tale, propogated by those who have a financial interest in scaring people away from a technology that has been used successfully in MAF equipped cars for many, many years. K&N, for example, has tens of millions of filters in active use in vehicles on the road right now and have been supplying these filters for over 37 years - says a little something about their credibility, doesn't it?

The very companies spreading the innuendo do not have the million dollar on-site SAE/ISO lab that K&N does.

Also, think about it critically: if oiled cotton were really a problem, do you think every car in the Indy 500 would run it? How about Champ Car? F1? If paper were really better at stopping dirt, why is it not used heavy dirt environments like in the Baja 500, 1000 and Paris/Dakar (motorsports dominated by oiled cotton cause filters like K&N and WORKS that have vastly greater dirt retention characterstics than paper or dry media filters). You would think that they would use the best dirt blockers available, right?

Looks guy's,

I have no financial interest in whatever filter I use.
Like I said, I'm just consumer.

Btw way, you can buy new K & N filters for $75.00.
I won't post any links here.

The truth is the truth, regardless of what is posted on this thread
and I feel that savy, informed members on this forum have the ability
to think for themselves. They ultimately know the truth.

Car's in competition can afford to replace components when they break
on a regular basis. whatever.

Until proven with unbiased empirical evidence that there is a reason the use oil foamed filters, I will continue use my HKS super hybrid filter on my Evo, the stock Toyota filter on my Toyota truck and the Fram, Mopar filter on my wife's Jeep.

Replacing the oil coated and crystalized MAF on my Toyota was not cheap, I've been there done that.

I'm done with this thread, Thanks for your time guy's

Jaime,
Great response. I try to ignore subjective comments from people praising a product they recently bought. I look for objective findings when trying to make a decision. I think you were able to do this, so I'm sold.

 

You dont need to oil it before installation right? I just dropped mine in.

 

Nope, no pre-oiling needed. Just plug and play!

 

When's mine coming IN?!?!?! Ordered it 5/30/06 how much longer do i have to wait jamie?!!? order Number: 422

 

any news on my DROP-IN-FILTER!!!!!!! Oliver??

 

Hello Rose,

Your tracking number is PM'd to you. Enjoy.

Hi, I ordered my air filter back in March and received an e-mail asking whether I was still interested in receiving the filter or not. I replied that I did want to receive the filter but have received no response, and my current order status is still "Processing." Any idea when this will ship out?

 

I checked that just now. Nine brands of air filters were used for the same series of tests. With the exception of the "No Brand" filter, I was able to verify that all the part numbers listed in the study all cross-reference to the GM Duramax 6.6L diesel motor. I couldn't find any info on the No Brand filter, so I can't verify that it cross-references. So, if you want, you can toss the No Brand filter results out.



Why does this matter? Only two tests were done using fine dust, and these two tests are not meant to be part of the coarse dust tests and are not in the results plots.



There are test data for it. Its the AC Delco A1618C filter in the first column of every table. Besides, its only used as a benchmark for two different measurements in the first table, and the absolute data are there too. The other tables are all absolute values.



The same nine filters are compared using the coarse dust. Two *other* filters were also tested separately with fine dust. The fine dust results are not meant to be compared with the coarse dust results.



Does it matter if the K&N was used? One of the selling points of K&N filters are that they are reuseable. If you are wondering whether they were cleaned and oiled properly, we may never know that. However, in the second table, the flow drop across a "used K&N 33-2135" is compared to the pressure drop across a "cleaned and reoiled K&N 33-2135". The pressure drop is identical in for both tests. Also, the K&N outflowed all the other filters at the start of the dust accumulation tests, so it seems reasonable to presume that they started with a clean filter. But who knows, maybe they did start with a used dirty one just to spite K&N.



I think somewhere else, you mention the humidity and temperature variations being an issue. All the tests were conducted within a 5F temperature interval which is plenty tight for an air filter comparison. On one of the three test days, the humidity was about 13% lower than the other days, but that small of a difference has no bearing on any of the results.

As best as I can tell, all the points of contention that you raise have no merit, and I see no errors, omissions, or cheats, perhaps with the exception that they used "course" instead of "coarse". :-) Now if they completely fabricated the data, that's another story. Do you think Arlen Spicer would do this?

So since you're asking whether its an objective piece of reporting, then assuming that the data are legitimate, then it looks extremely objective to me. Do you know of other issues that would invalidate these tests?

 

Just curious. How often are you supposed to clean and oil the works filter?

 

I believe every 3k miles depending on your areas climate (excessive pollen,dust). I check mine all the time just to see how much debris its been collecting. If theres a lot of crap in there I'll just shake it all out. But I dont think it needs to be reoiled for about 3k miles.

 

3000 miles?! No way - it's got to be more than that. I'm curious now too. Anyone have a definite answer?

 

I just got mine on saturday and oliver told me to clean it every 15,000 but if I was in dirty/dusty areas I might need to do it more often. I guess you can just pop it out every once in a while and inspect it.
