If I remember correctly, our stock plugs are the coldest possible, the same plugs as used on the Ford GT race car. I think our stock plugs (not on normal Fusions, but definitely on our Sports) qualify as performance plugs. 馃槈

In fact, some people have bought "special" plugs from tuners then figured out with our cars they're actually the same plugs as we run stock. 馃槀

Yep. I fell for plugs advertised as 鈥渙ne temperature range colder鈥 boondoggle.
As my old Pappy used to say, 鈥渃older than what?鈥 should have been the next question. My car eats plugs for breakfast and the most durable and best at holding their gap that I鈥檝e found by trial and error are the Motorcraft plugs**.

From reading around here (I just bought a 19sport) the PTU fluid should be changed like now lol

Actually this is not true on the MY19 Fusion Sports. They did NOT come with the colder plugs from the factory:
Heads up to all 2019 Sports, you may have the hotter SP-578 (CYFS12YPT) plugs from the factory like I did | Ford Fusion V6 Sport Forum (fusionsportforums.com)

PTU fluid is easy to change, I do mine every oil change. Takes about a quart, have yet to see anything even close to dirty looking or burnt smelling. I think I can go every other oil though, and still be doing really good. I need to do my RDU though, that's next on the list with the next oil change

I know the importance of keeping the PTU oil fresh but every oil change? it's probably still the same color as new! lol
I think every 10k should be sufficient.

I was shooting for 10,000 between changes.

How many miles on the car?

I change fluids relatively often and my tune didn't change that schedule. I literally did nothing for the tune - I had new spark plugs but didn't need to put them in as the car ran great right from the moment I installed the tune.

I bought it last May with just a tic over 16,000 has 35,000 on it now, So I changed it at 20 and 30 so far. Oil wise, I,m shooting for 20% left on it when I change that, which I,ve been doing pretty good hitting. Just have to check the oil minder every once n while to see where your at, I,m about do for a look.
