Thanks for posting your list Big O Dave. I tried to link to the Oil Guy site and it would not work. Here is my Purolator L40017 data (used filter vs Big O Dave's were new) next to Dave's FL-299 data:
Code:
Filter Pleat #Pleats Element Element
Depth Width Area
FL-299 0.750 64 5.50 528.00
L40017 0.719 66 5.38 511.00
BTW, someone at this site a couple years ago posted that the longer FL299 was spec for IIRC an '89 F850 with 460 V8 (among many other years and models obviously).
I use the L40017 on my motorhome and sometimes on my 300 I6. Not to leave the very good FL1A behind, I am running that on the Aerostar 3.0, which specs a FL400.
