maintenance schedual

I was looking through the windstar maintenance schedual, wondering what you guys thought about the published numbers. this is how many miles between
replacement.
air filter 30k fuel 30k trans 30k - so their saying to replace all of the fluid every 30, I assume do a filter at the same time. Should a filter with those 5qts be done more often? coolant 30k plugs 100k- you can go 100k between plug changes? is this even after the originals are pulled, does it matter what brand they are replaced with?

Just my $0.02, some of this may not work for you ...

Inspect filter every 10k mi. (5k if your roads are unusually dusty). You'll likely be able to tell when to replace.

Not unless there's a specific fuel-related problem.

I got a 4r70w (that I've never fully trusted). When I check oil, I check tranny fluid for color (kinda light red), consistency, and smell. If something's funny, (i.e. fluid smells "burnt") I try to figger what/why, maybe change earlier than 30k.

I haven't.

Similar to tranny. Inspect several times/year. If color is OK and coolant smells like rad. hose and no particulate matter, scum, etc, then consider change at 30k anyway.

I'd venture a definitive "Yes" to this last.
Hard for po' me to imagine 100k on a set of plugs, but I'm driving a 12-yr-old 'Boid, lotsa things might've changed.
If motor runs fine, I'd pull a plug or 2 and inspect electrodes every 40k mi. Lotsa stories are told by appearance of plug electrodes (Google'd help with this). More often if motor runs funny.
Seems most maintenance schedules are OK as generalities. I usually like to look a little closer ...

If you use Platinum plugs, they can last 100k
