It's beveled, never saw that before yesterday in the store. The base almost looks like the ecore base without the extra cover plate.

I've seen lots of round ones, never one that was triangular like that.

Should seal fine. For the same torque you get higher pressure (PSI) on the smaller lip than a wider one. On their side, I can also see this as a way to reduce the amount of rubber per seal.

Looks like a 10-15% reduction and that could add up to big bucks on a high volume market. Good value engineering in my opinion. lower cost and marginally better performance.

Just don't overtorque these or I suspect the small lip will tend to stick due to the higher pressure.

Been that way since the newer ST 9688 hybrid design filter introduced as seen in 53' dissection linked. Champ decided rather than narrow gasket inside OD used on most 9688/3593a, extend it to OD.

Is this what supertech recommends as a 7317 replacement? If I remember there is no ST7317 correct?

If you look in their books or the little computers it recommends the 6607 size.

Correct. No ST7317 is available.
They recommend a 9688 for every 7317 application I've seen.

For less than a dollar more, you can get a NAPA Proselect with silicone ADBV and built like OEM. I paid $3.49 for it..... #21334

No and yes. It's true there is no 7317 application the ST line however the shorty 6607 is what ST consolidates for that application. The topic 9688 is too wide for many 7317 vehicle applications now. Many newer Honda and Nissan have block, pan and/or diameter restriction rings that prevent the wider 9688/3593a from being used, screwing on. The 6607 will always mount on a 7317 application vehicle.

The 9688 is the common size for Hyun/Kia with spin on filter application, eg., 2.4L engine.

The previous ST line made by Champ, years ago, did have a 7317 application.

As an aside, the AZ STP blue filter line used to be very similar to or same as current ST line, they too had no 7317 application. Since the new manufacturer with China coo, the blue line now has now added a 7317 application.

Are we talking the can is too wide or the gasket?

The reference to 9688 being too wide and restriction is in regard to the outer diameter (OD) of the 9688/3593a can.

Pic shows a comparison of the more common standard 9688/3593a baseplate and 7317 application size side by side.

That probably is the reason, to maintain contact diameter. The sealing pressure should be greater since the thicker rubber concentrates it's power into the narrower band. the other observation is the base plate looks like ecore without the extra metal cover. I like the look of the ST filters they are going forward it seems. Maybe because Champ has this very fat WM contract now.
