Towing no different.
In town no different.
Running smoother? Maybe...
Changed too early? Yes.
Peace of mind knowing this? Some.
Harm caused. Zero.
I guess 6 stock equally gapped plugs to. 040 is just as good as 6 upgrades at. 032 in my truck.

For those that has bought the SP-534 plugs, can you tell me what the service number is? It's that CYFS something something number. I just want to compare it to the SP-528 and SP-519. For some reason, when I stopped by my dealership and bought replacement plugs, he gave me SP-519 and said that Ford specified them as a replacement for the SP-528. From what I see, the SP-519 is standard on the 5.0 engines.
From what I can tell, the only difference between the SP-519 (CYFS-12Y) and SP-528 (CYFS-12-Y3) is the last digit designation, which I understand to be the pre-gap spec?

Thanks a bunch! So it looks like pretty much the same specs as 528 and 519. I wonder though, what the 'T' designation stands for. It's not listed under the Motorcraft Spark Plug Model Number Identification chart that's on the interwebs.

So I'm pretty much a novice when
It comes to working one truck but I'm about to gap my plugs to .030 for my tuned 2013 ecoboost today. Any advice ? Or Anything I need to watch out for ? Is it pretty easy ? Thanks

It's pretty easy, just be mindful of the torque when tightening them in. They might be a little snug taking them out so just ease them back and forth a bit until they start coming out.
