[DeTomaso] good oil filter

The resistance to flow even of air thru a tube is inversely related to the diameter of the tube to the fourth power. (If you decrease the diameter to half, the resistance goes up to 16 times what it was.)
So the diameter of the openings will be the primary determiner of the resistance. It would be interesting to see magnified views of the filter material in the single-use and rebuildable filters to see how the latter can provide lower resistance with equal filtration.
In the BMW community, the expert mechanics pretty much accept that OEM air filters do a better job than reusable ones in terms of engine life expectancy.

They claim that the reduced pressure drop is the result of using a better
iltering material, and achieve the same filtration.

en,
he critical question here is whether the pressure drop is less at equivalent
icron filtration. It's all about getting a viscous liquid across a fine
iltration membrane, the problem is most manufacturers sacrifice filtration
ineness to get the lower pressure drop. That may not be all bad, but one should
nderstand the pros and cons.

I recently talked to a couple of the reuseable filter makers. They aren't
heap, but may have one significant advantage for a Cleveland. They claim
he pressure drop across their filters is a lot less than the drop across
onventional filters. That would seem to be a really good way to get more oil
low without a high pressure or high volume pump that adds to the load on the
istributor gear and pin.
If anyone has gone to one of these lately, according to the manufacturers, you
hould have seen higher oil pressure.

I just tore some new Frams apart last fall. Bad.
The K&N HP-3001 seems pretty good.
The price varies a great deal though. $11 to $39
K&N HIGH PERFORMANCE GOLD OIL FILTER -- Canister type, 5.7 in. H, 1.6 lb
weight, 3.65 in. OD, 0.75 in. thread ID, 8-11 PSI relief valve; Includes
anti-drainback valve, and bypass valve; Developed for demanding race
applications that uses thicker canister walls for extra strength and
durability for reduced risk of damage from lose rocks and debris; Uses
cellulose media that traps 99 percent of harmful particles; High-flow
design helps reduce engine drag; Offers maximum filtering surface,
prevents filter collapse, eliminates dry starts, and leak-proof double
roll seam; Features sturdy 1 in. nut for easy removal, pre-drilled
safety wire attachment, and heavy-duty 5-gauge steel for extra
durability; With K&N limited warranty.
*Type:*
Canister
*Part Number:* HP-3001
