K&N Filter Effectiveness, from oil analysis

[Gunmetal5oh]

TOTAL DIRT PASSED: K&N scored near last, passing 7 GRAMS OF DIRT

This is an ISO test, performed independently from K&N, in a controlled environment using the most precise equipment available.
I will take this evidence to suggest there are better filters available.
A K&N will give you less initial restriction, but that's because there are holes in the filter big enough to let dirt get right through.

I also have data to instruct you all on how to "remove foot from mouth".

Does anyone have any evidence that a K&N filters fewer particles than a paper panel filter?

Last I looked, most OEM panel filters filter down to about 9 or so microns.

A lightly oiled K&N filters down to roughly 1 micron with initial efficienty over 97% and overall over 99%.

I'm not sure where all the, "OMG you'll wreck your motor"!!! stuff comes from.

If you live in the burbs and drive a bone stock whatever... yeah, a K&N might be a waste. The size of the OEM panel will outflow your motor every day of every week.

If you're trying to squeeze every last ounce of restriction out of your 3 or 4 inch inlet tract... well... now the size of that OEM filter panel isn't such a great thing anymore.

Either way, a filter done wrong whether it's an OEM style paper filter or pleated conical K&N, can and often will give you issues. If you're not a, 'maintainer' of your filter and inlet tract then you shouldn't have bought that CAI with aftermarket filter in the first place. If you're idea of modification is a set of platinum sprak plugs and a fart can, then you also have no business running an aftermarket. Stick with replacing your OEM panel at the recommended interval.

If your modifications have exceeded the inlet tracts ability to support your combo then it may be time to go aftermarket. Will I install a larger airbox capable of a larger OEM type paper filter? Oh hell no... let's just take the trip to Bizaro World instead. I'm going to install a 360* reusable filter and maintain that filter as is recommended.

As for law suits? Uhhh... Ok, whatever. I can sue my neighbor for stepping onto his front porch in boxers and flip-flops to pick up his morning paper. Doesn't mean I'm going to win.

...just like the Amsoil you keep bringing up. It was more to poke fun at you because you SEEM very susceptible to simply going along with everyone else. Sounds to me like you were molested by an Amsoil salesman at some point in your life, because you're way off bud.

My favorite part of this is that the first graph posted above by Mr. Gunmetal is linked from an Amsoil dealer's personal website. Bill's WEB SPACE

ok how about this... i could care less about 7 grams of dirt going through my motor i change my oil once a year. how much more air flow you getting from a K&N over an AC delco?

 

[srtthis]

also... you posted who did the test...

who paid for it?

test data is very very very easy to sku

Goober, do you also believe in magic bullets and aliens abducting people?
That article is hosted on dozens of different websites, it has nothing to do with any particular company.

Your effort in trying to make a correlation or connection to amsoil is idiotic.
There must be something in the water in Seattle.
