Hi Guys, Sorry to bump this one time, but I am worried about the slightly different tops to the Bosch filters. If nobody remembers about this I will just get something else. THANKS
I tend to hoard parts that I think I will (or might) need. Well, I had accumulated several of the oil filters that were displayed on the "list" in the beginning of this thread. I was organizing today and categorized my stash of filters for our cars/truck/bikes.
In doing so, I ran across post 12 in this thread, which shared that PL14612 now has a shallower base which prevents the oil seal from completely sealing : List of compatible oil filters for 650?
In the same thread, I ran across post 17 that confirmed fitment of Fram TG7317.
Conclusion to the filters I had on hand for comparison....
Fram 1365 (Gold), Fram 31365 (Silver), and Purolator PL14612 all had a measurably shallower base, when compared to the Fram TG7317. Based on the measurements (oil gasket surface to thread distance), the Fram 1365 (Gold), Fram 31365 (Silver), and Purolator PL14612 are nearly identical. In other words, if the new PL14612 has too shallow of a base...then the others do too.
The difference when comparing these to the TG7317 was about .06 inch (roughly the thickness of a penny). The TG7317's thread base to (uncompressed) seal lip distance was about .25 inch (almost perfect equivelant of 2 quarters, 1 nickel & 1 penny stacked).
The last filter I used was a K&N, so I've not tried any of these above for actual fitment. Based on measurement and feedback, I'm considering taking the Purolator and NAPA filters back for exchange.
Can anyone confirm issues of fitment with the NAPA filters I've listed? I find it hard to believe the PL14612 will no longer fit appropriately, if
the NAPAs will.
