Anyone have recommendations for spark plugs for 2010 5.4L. Looking at changing mine.

Can never go wrong with motorcraft. But I recently replaced mine with e3 plugs and so far so good.

I installed e3 in ours almost 3 years ago. No problems in 23,000 miles since.

Not for a 2010.. 5.4 3v motors built after 10/09/07 had the redesigned heads and require the SP509 and brown boots.
