There have been studies done that show Fram quality is not all that great. Do a search on this site around
oil filters and you'll find the thread. I would go with either Motorcraft® FL-1A (standard filter you can get at any auto parts store, but good quality) or their racing filter Motorcraft FL1HP (probably have to order from Summit or buy at a Ford dealership, but you can buy individually). From what your builder recommends, sounds like the FL1HP would be the right one.
