What kind of oil filter do you guys use?

Wix is still made here, and many other places. As stated, they have gone the "global" scene.

Motorcraft is still made in the USA as of right now. They are good filters, too.

Damn skippy Robster,

FoMoCo's FL1A after all these years is still a re-branded 51515 !!!
Hell lets paint the can pink, black, lemon yellow, or put flames & orange pokka dots
on it.

some dumb azz said
Single Most important caveat here however...
Wix --- North American Production --- is made in the USA, & DOES NOT SUFFER from
the ... mmmm... latency of overseas quality control groups.
