I'm doing a filter pressure drop test on these filters in the near future for another website. I'll post results here when the testing is done.
For what it's worth...........these filters fit the VTX also. The long versions will require some effort to install and remove due to thier length. If you want no problems use the short versions.
OEM filter is part# 15410-MFJ-D01
After market filters:
AC Delco PF1237
AC Delco PF2135
Baldwin B1400
Bosch 3300 short
Bosch 3323 long
Firestone TF2876
Hastings LF113
NAPA Gold 1365
Napa gold 1358
Purolator PL14612 (Short)
Purolator PL14610 (Tall )
Purolator ML16817 (Motorcycle filter)
STP S-02876
WIX 51365
WIX 51358
Mobil 1: M1-108 short
Mobil 1: M1-110 long
Carquest 85358
Fram PH6017A
K&N KN 204
Wal mart Super Tech 6607 short (discontinued)
Wal mart Super Tech 7317 long

The Mobil 1 M1-110 just fits on the 1800. Clearances are tight but it doesn't jam if you line up to the threads first. Just strictly a personal preference but I like the longer filters in the hopes that more filter media means more trapped garbage and a cleaner engine with less pressure loss. But I don't have anything like facts and figures to back that opinion up.

Well, you do have the fact that we have used the Mobil 1 M1-110 filters on both our VTX bikes (1300 and 1800) for several years and have had no problems at all.

That's why I'm doing a pressure drop test on these filters.
While it's obvious a longer filter has the ability to trap more debris over its lifetime, it is unclear if the longer filters offer more or less drop, simply because of their length or the type of filtering media they use. Some have stated just the opposite because on the premium filters like Pure One and Mobil One, they do use a different filtering media which filter out small micron size particles but cause higher pressure loss through the filter. If a filter is more restrictive, this lowers engine lube pressure to the engine. That's a bad thing.
There has been so much misinformation about using aftermarket filters on this site and others I participate in, I decided to perform an accurate test on many different brand filters to determine what the actual pressure drop is across them. I'll use my Goldwing as the test mule because it's so easy to perform the test on it but the net results would be the same on a VTX or any other engine. We're testing the pressure drop difference of each filter using a common testing device (the Goldwing) while performing a standard reference oil pressure test procedure as per the Honda manual.
Some have claimed some aftermarket filters produced as much as 20 psi less than OEM. That is significant and can cause long term engine damage which would not be apparent in the near term if using them. As modern design engines use the head material as the bearing surfaces for camshafts, it's critical to maintain oil pressure at these clearances or damage will result. Once these clearances are damaged, you have to replace the entire head because they don't use replaceable bearings. Hence the need to maintain OEM spec oil pressure. Personally I would not want to see a reading of more than 5 psi below an OEM filter reading.
I'll do the test when I get back from Daytona.
As of 3-7-12 looks like WalMart has officially deleted the SuperTec filters that fit the VTX from thier stock. These were made by Champion.

Not sure why this thread got bumped without a new posting. Didn't know that could happen.
Since it did I'll update what going on with the test.
I've beeen having problems determining what the oil pressure switch thread pitch is so I can adapt my gauge to the engine in order to do the test. Bought an adapter from AutoZone with what I thought (and was told) was the correct thread..........it wasn't. So I tried to order the Honda adapter stated in the manual. Honda of Houston nor Wild West can identify the part number and are no help. Today I bought what I think is the correct adapter. Hope to do the test this week if I have the right adapter.

WTH??
Wha happened??

Wow!
Someone responded to this thread five years after the last post.
I did complete the oil filter test using my Goldwing but I haven't posted the results here. I'll get it from the Goldwing site and repost it here. From what I can remember, there was very little difference in the filter pressure drop values among all of the filters I tested. Even the most restrictive filter that filters out the smallest micron size particle had very little effect on oil pressure.

Good to hear from you Mike
