My personal and very UNscientific air filter flow test

[AccordMDX]

Well I thought I'd just throw this out here.

When comparing two or more filters I think you could get an idea of the amount of relative air flow restriction of the filter by blowing a puff of air into one side of the filter and feeling it by the palm of your hand on the 'engine' side of the filter.

I had chance to do this when I was replacing the oem(Filtech, green color) air filter for the MDX. I put in a new NAPA GOLD. With the oem filter the air hitting my 'test' hand was much less than that with the napa gold. Additionally I could feel the air bouncing back on my face with the oem filter but not with the napa gold. So I conclude that the napa gold is a better flowing filter than the oem.

Did you compare the used dirty OEM filter to a brand new Napa Gold?

That made the "test" even more unscientific than it already is (I don't know if it's possible though).

fwiw it had very low miles on it and so it wasnt that dirty. I was intending to replace it since the day the dealer gave me delivery of the vehicle(~5 months ago). But since it was a brand new filter I thought I'll live with it for a while.
