Has anyone ran RUTHENIUM HX in a 2007 5.4?
I see some thread post of like 2017’s and newer, running NGK‘s. But I’m wondering if anyone has ran NGK’s on the 2007 expedition Eddie Bauer edition. I’d really like to try to max out performance and hopefully get a little bit better gas mileage with a better spark which I think the NGK’s would do.- wildcard007
