LOL. You call that proof of concept? Thats pathetic. I don't care how dirty your airfilter is. You want to prove anything? Use a wet cleanex to wipe down the entire inside surface of the upper airbox. Lets see what got through your Precious K&N.

Heres mine. Volvo 960 airbox with the stock Mann/Mahle paper filter changed out every 30k miles. The car has 150k miles. The airbox has never been cleaned.

1000 miles on the filter.








I'm tired of hearing all the k&n marketing bull. Time to put up or shut up.

The problem with your theory is, a k&n filter doesn't flow any more air than any ordinary paper filter. Its been proven time and time again by independent test most of which have been linked into this thread.

Time to put up or shut up, boys!!!

I ran outside a took some pics of the airbox/filter in my DD...

This filter is 8 years old - been on two vehicles - 200,000+ miles - never been cleaned, just shook out and put away wet!
I don't see how those pictures prove anything, and how the study I linked to is BS...

People are free to believe anything they want. In this case they can chose to believe some guy with an old filter or the results from an ISO test done by an automotive filtration testing equipment manufacturer...

I use a Wix air filter on advice from a member of another forum. Had a K&N, unable to detect any improvement.

So at this rate it would take 5 paper filters and 150k miles to even begin to recoup the initial investment in a k&n filter. That doesn't include the recharge kit or the cost of shortened engine life due to k&n's pathetic filtering qualities.
Some deal.

Ask ANY woman, if you don't believe me...

How many paper air filters have you blown through in 8 years?

Don't overestimate or underestimate! I'm just curious...
My TDI is on its 3rd oem air filter at 203k miles. I use a CAT filter minder to know when I need to change my filter. The current filter has been in for the last 53k miles and is pulling roughly 20 inches of water.

I must have glossed over it. My apologies. Better than I expected but still doens't help justify the expense of a k&n.

This sort of goes back to the concept of "lifetime fluids". Something a lot of European manufacturers were in love with in the mid to late 90s. It didn't work out too well.

It all comes down to dirt intake, not power/economy. I prefer a clean engine and a clean filter that I can replace for about $10.00 a year. Let's not make a big deal about air filters because what is an air filter? Exactly, an air filter.

I agree. Is it worth going at it about? Is it that big of a deal?

I did see one thing that makes sense to me... Disposable filters have to go in the landfills. That's a simple, honest point. I admit, it's got me thinking of changing.

Actually, the K&N outflows the paper filter, (I believe the Duramax test validates this - can't get to it from work to validate) but the K&N allows more dirt in.

Air Filtration Test

Quote: For the record, the K&N was the best flowing filter.

No angst here, but if your air filter (on any car) is a flow restriction, a better flowing air filter will increase performance.
