03 Ford 5.4 fuel pressure

I don’t remember my stock ones having any writing on them. They were just solid black but it’s been a few years since I’ve changed them. I replaced them with msd and those only lasted exactly a year. Motorcraft is the way to go.
 
Ha, I totally called it.

So was it the intake gasket or could(s)?

Originally one bad china coil...after all the work and coil swap one bad original coil (that was replaced at some point also). Plugs looked normal so. Intake gasket was very worn (230k miles) but no actual visual leak.
So I didn't spend $60-90 diagnosing fees rather ended up spending little more on the work I did today so glad I took y'all's advise once I had the time and just did it
 
Coolant in those plugs must've been from earlier this week when I changed heater bypass valve
