The only problem with the LF3918 is it's pretty dang long

Largest OD 92.96 mm (3.66 in)
Overall Height 175.77 mm (6.92 in)
Thread Size M26 X 1.5

But yes all the microglass preforms about about the same. 98% * 20 microns and 50% * 7 microns.

The none microglass version is the LF3746

Baldwin makes a dual flow version of that filter that is similar to the BD7317 I posted earlier and is a 50% at 5 microns
BD7095

Thread: M26 x 1.5
O.D.: 3 11/16 (93.7)
Length: 7 1/8 (181.0)

This could be a great find for if it will fit. These are double the size of your normal OEM filter, the Baldwin is a true bypass filter as well and would give you around 8000klm over the fleetguard. It also has a microglass media.

Guess it would boil down to price and availability.
