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