3 oil filters compared

Well, i got my snazzy oil filter cutter, and opened 3 filters in my garage:
1) A Honda 15400-PT7-005 (Fram?)
2) A Honda 15400-PCX-004 (current S2000 filter)
3) A Denso 150-1006 sold on a Honda parts site as "better than the cheap Fram filter Honda is selling".
Let's count pleats:
1) 47
2) 53
3) 47
Advantage: Honda S2000 filter
Let's measure the filter media height:
1) 53mm
2) 53mm
3) 44mm
Advantage: Hondas
What about external flow holes?
1) 6
2) 8
3) 8
Advantage: Honda PCX & Denso (combined with the internal holes, these 2 clearly have higher flow capability)
Symmetry of pleating:
1) Good
2) Fair
3) Excellent
Advantage: Not sure. Are symmetrical pleats better?
Bypass valve material:
1) Treated paper
2) All Metal
3) Plastic
Bypass diameter:
1) Approx 19mm
2) 20mm
3) 10mm
Advantage: Honda S2000 filter
Bypass valve tension (estimated):
1) Moderate
2) Higher
3) Moderate
Advantage: Honda S2000 filter (assuming higher tension means less bypass/higher oil pressure needed for S2000 engine - clearly not an "all-purpose" design
Internal holes (for oil flow)
1) 104
2) 220 (slightly smaller than #1)
3 165
Advantage: Honda S2000 filter - Denso close with smaller filter size
Filter media depth:
1) 12mm
2) 12mm
3) 12mm
Advantage: Both Honda filters had more surface area
End seal anti-drainback gasket material:
1) Silicone rubber
2) Silicone rubber
3) Silicone rubber
Advantage: None - all had fine quality materials.
Oil flange mating gasket:
1) O-ring type with torque limiting design
2) O-ring type with torque limiting design
3) O-ring type with torque limiting design
Advantage: None. All had quality gaskets unlikely to leak if properly torqued using the "7/8's rule".

General analysis of filter quality"
The generic Honda (#1) had a cheap bypass construction, cardbard end caps, and fewer flow holes. It appears to be a typical Fram filter.
#2 was all metal, and had indications of having been purpose built, especially based on the size and opening pressure of the bypass valve, and the number of flow holes. These are important to maintain proper oil pressure and ensure bypassing ony when needed.
#3 was well made, but the smaller filter area and the narrow bypass suggest this filter was not specifically designed for the S2000.

Destiny, yes, that's right - I only got so "deep" into the analysis, so yours is a nice build. It also strengthens the point that the PCX filter is a dedicated design, not a universal. For me to use anything else, I am going to have to see a lot of similarities between the contender and the PCX.
