Obsolete Oil Filter?

[birdman]

I don't mean to start a debate about oil filter brands, but can anyone tell me if the Motorcraft FL-218 oil filter is still made? That's what came on my T-Bird when it was new so I just stuck with it. In fact I purchased a case of the filters back in 03. I still have enough to last a few more years, but I did an internet search for the filters today and some sites say the filter is obsolete. No, I haven't tried a Ford dealer yet. I was hoping to find a better price on the internet.

A well known auto parts store (site) recommended the Motorcraft FL-2021 oil filter for 02/05 Thunderbirds. If anyone has tried that filter can you tell me if it has the same oil capacity as an FL-218? I would like to stay with the larger size if at all possible and I'll probably buy two cases this time. Thanks in advance for any input!
