Jon Satterfield purchased and dissected several filters for Honda Motorcycles. We all owe him a big debt of gratitude. Here's his results:"Finally caved and picked up some Super Tech oil filters."
I just wanna' know how well the filter works...
Filter Surface area Sq.In. Filter Thickness Relief Valve PSI Case Thickness Drainback Valve Comments
AMSOil
SMF 103 36 .038 25 10 mil nitrile Internally contaminated with dirt particles when new. Excellent filter media, but not much of it.
Bosch
3323 82 .038 25 20 mil silicon Very good filter media, similar surface area to stock filter.
Mobil-1
M1-110 60 .038 25 20 mil silicon Excellent filter media, but only 2/3 the surface area of a stock filter.
Pure One
PL14620 110 .030 17 20 mil silicon Excellent filter media, and there's a bit more of it than stock.
SuperTech
ST6607 41 .023 18 10 mil nitrile Comparable to an OEM filter, but $2 instead of $13.
Toyo Roki
OEM 94 .035 18 20 mil nitrile Decent filter media - not up to the standards of the Purolator, Mobil-1, or AMSOil, but there's a lot of it.
