Looks like the K&N flows significantly worse than an oem filter. Goes directly against their marketing claims.

Not surprised. If KN had some magical feature that increased MPG or HP, they would have been bought out years ago. Simply a marketing ploy.

Did either of you guys or the OP actually read the whole study? she conclusion at the end reads

"The acceleration and fuel economy tests conducted on the vehicle shows that the vehicle performance will be
slightly better when the filter is new compared to that when it is clogged. The fuel economy tests shows that K&N
air filter provides a better fuel economy compared to OEM style paper filter in both new and clogged condition. The
acceleration tests also shows that acceleration times for K&N was slightly lower than OEM style paper filter in both
new and clogged condition"


So the independent test basically confirms exactly what K&N claims as the reasoning that anyone should purchase their product. All the other parameters that the experiment purports to test, on just a single small engine like a mower would use, are somewhat meaningless to most vehicle owners.

Fuel economy is improved because there is less flow of air and therefor less fuel being injected to maintain the stoichiometeric ratio. K&N doesn’t market fuel economy gains nearly as much as better flow and more power, which this study directly opposes.

The filtering efficiency test conducted on OEM and K&N air filter shows that OEM air filter exhibits superior air filtering qualities compared to K&N filter.

From real Indian scientists. If you're into filtering efficiency testing.

Yes, they also noted an increase in motor vibration after installing the K&N...
We all know how much a change in air filter affects motor vibrations Coffee

In some ways opposite to this YouTube piece.
K&N provided more airflow/power, but less effective filtering.
Confirmed my thinking on K&N.
WIX for the win IMO.

Every application is different. K&N works for some and not for others. It's far from a marketing ploy.

Agreed, that's how I read it too.

The YouTube guy "Engineering Explained" showed the same thing.

It's v. simple. K&Ns 1) flow more air and do deliver some additional power to many vehicles and 2) conversely let more dirt in to obtain that higher flow. It's not rocket science or controversial, it just "is". The question has always been, does the small drop in filtering efficiency matter to you/your car in your driving conditions? To me, it does not and I welcome the slight, proven gain in power on my tuned/modified car. If you don't like the little bit of extra bits getting in, cool, use a paper filter. This will not ruin or reduce the life of my engine and my car will fall apart from old age or me blowing it up sending it before that slightly lower filtering efficiency will ever come into play. The end.

Agreed, and will add that it isn't only tuners or performance enthusiasts buying these anymore. Some just like the sound, the environmental aspect or all the above.
