Oil filter used and why?

[Shootnride]

Well, you know what they say about opinions.....but you asked, so I'll give mine. I believe that the OEM's put a lot of R&D into designing their oil filters and they have very sophisticated resources for testing that most aftermarket manufacturers don't. OEM's also have a vested interest in producing a quality product.....they're not fond of replacing engines under warranty. For purely racing applications, some of the aftermarket choices are likely a better choice than the OEM filter, but most of us aren't racing. I personally use Motorcraft filters in my FE.
Just my two cents.
