Does anyone know if there is a difference between a Motorcraft FL-1A oil filter vs FL-400s filter. I've been doing a lot of research and people say the FL-400S is a much better filter. It's getting almost impossible to find a FL-1A but there are a lot of FL-400S filters out there. I have the 4.0L SOHC.
