Looking for any good ideas or help with fixing up the ride a bit. Thanks in advance!

What do you have, other than stock, and what is your goal? Here is a recommendation for one heat range colder than stock https://www.steeda.com/Ford-Perform...Set-35L-Ecoboost-F-150-2010-2017_p_14143.html

I don’t have a goal per say, I just didn’t know if there was a brand out there that is preferential to others out there. I need to replace them and if I could get any guidance or focus I thought I’d ask.

I like motorcraft for plugs. If you’re not tuned just get OEM.

Agree I love OEM Motorcraft in my Ford vehicles. If you turn up timing and boost then you might go cooler and see what fits. You need the right heat range and plug height to make sure the coils fit right.

Speaking of, I was having trouble finding SP-542’s. (One heat range cooler)
Sure there were some on amazon and eBay but there are too many counterfeits out there to trust that. Found them at Home Depo of all places.

I think they have a marketplace type service that is similar to the other outlets. I'm not sure if they authenticate those products. Maybe? Wal-Mart makes me wonder also. Tough to figure it out.
