I've noticed a few Fram Ultra filters don't seem to be stocked anywhere, does anyone have any idea if they have they been discontinued, or if Fram just requires some sort of large minimum order and nobody orders them because the low demand.
The Fram XG30, the short filter for Chevy smallblocks, can be replaced with the longer XG5 .
The Fram XG3675, which is used on tons of GM vehicles, can be directly replaced with the XG9837, the 9837 is the same size as the 3675, it would normally not have an ADBV but all Ultra filters come equip with an ADBV it can be used in place of the XG3675.
The Fram XG2951, for a handful of Suzuki V6 engines and some 80s Toyota engines, it is the pretty much the same size as an XG3614 but has a different tapping plate to accommodate a smaller diameter gasket, would've been a good choice for an oversize in applications that call for an 4967 or 4386 size filter that don't have a large enough mount to accommodate the larger gasket of an 8/16/3600/3600 size filter .
Anybody notice any other hard to find Fram Ultra filters and found a suitable replacement for them?
