SPARK PLU INTERCHANGE

2002 Ford F-150 • 5.4L V8 2WD Automatic • 41,000 miles

At a local parts store I ask for plugs to fit a 2002 F-150 Harley 5.4L Supercharged engine. They sold me SP-479 ( AGSF22WM), installed them, while glancing thru owner maintenance saw where it listed the AGSF12FM1. He said he looked up for a lighting thinking it would be the same, as you know it's a pain to change them, will the plugs interchange and if so what is the difference is in them? I have not even started my truck until I know what to do. Thank you.

They will work but it's the wrong heat range for the truck. They are to hot take them back.
