7317 vs 3593a on honda k24

[sumptimwong]

i recently did a oil and filter change on my 2005 accord 4cyl, and noticed that i accidentally bought a ST7317 instead of the usual ST3593a that i usually get. i was thinking baout going back to walmart and getting the 3593a for a mid-oci filter swap, but decided to look here for some advice first.

what ive read has basically said this:
- 3593a is much bigger in voluem compared to the 7317 (this i noticed, and was what concerned me)
- while the 7313 is physically smaller, people seem to believe that it has almost the same amount of filtering media
- the gasket on the 3593a is larger than the OE gasket, which could potentially cause oil leaks depending on your application (ive already used a 3593a without any apparent problems though)
- 3593a has a clicker-type bypass valve
- 7313 has a leaf spring bypass valve (better?)
- both have M20x1.5 threads, which is why they are "interchangable"
- bypass psi is slightly different?

for the record, supertech recommended the 7317 size filter for my car, which is about the same size as the newer (smaller) OEM 15400-pcm-a02 filters.

just wanted to see what you guys think about this one. lots of great info on these boards, and knowledgable members. i really enjoy this board, thanks in advance for your help.

also, has anyone posted results of a filter cutaway for this comparison? if not, id be happy to sacfrice the whopping $4.14 for two ST filters and take some pics. can someone briefly describe the best way to cut up a filter? i have a dremel and some disks, is that suitable?

I thought the 7317 gasket diameter is the same as the 3593a in diameter. Do you just mean the rubber gasket itself is thinner than the other one?

 

[sumptimwong]

at least ofr the supertech filters, the gasket diameter for the 3593a is significantly larger than the 7317.

i dont have a filter, chain, or pipe cutter. where can i buy something cheap for a one-time filter cutting use?

The filters, IMO, are interchangeable. Don't worry about it.

Most automakers are spec'ing smaller filters now and back spec'ing for other previous years. I prefer bigger filters if available.

Use a filter, chain, or pipe cutter. Some fancy can openers might work. If you use your dremel, you'll make a mess. Sometimes the mess is confused for manufacturing debris.

Wow, great. Thanks for the link!
