Full is its own company. It is an off-brand asian make, available via the worldpac sites and other similar places. I found their quality to be OK, but their designs to incorporate reduction of materials to keep costs down.
For example, when I bought an oil filter for a 94 integra and one for a 94 previa, they were much smaller than the nippon and denso and OE branded filters. Ditto for air filters.
Id go with the main brands, i.e. wix, mann, hengst, mahle, purolator, denso, nippon, etc.
Never heard of them. Buy one and cut it open and post here and we shall figure it out.
+1 Size makes little difference. The only problem is evaluating the quality of the media. I cut open the OEM thimble off my son's Miata. It had twice media of a Fram 4 times its size. The newer Purolators have followed Fram down the road of a big empty can.
