wich boots?
changing COP's on my 2005 F150 with 3v 5.4, my searches say brown boots were only 2008 and up but mine has the brown boots. i have put the one piece plugs in but the boots/coils have never been changed. do i order the brown or black booted coils for these one piece motorcraft plugs

Nope, those use the black boots. DG511. Brown boots are for mid-2008 and newer with SP-509 plugs, DG521.
The SP546 are still 2 piece, they are more resistant to breakage.
The only reason I asked about the plugs is to eliminate the possibility that the heads or engine were not original.

Truck all original, i bought from original owner, wich i knew very well with 58,000 miles, he had never done anyfhing but oil and filter changes. I put the plugs in 1 year ago at 152,000, never paid attention to boot colors. Had a COP on number 7 going bad, was going to order all new set and noticed black and brown available. Pulled number 7, it was brown so ordered brown boot set from D.U.I

Look at the pictures I posted. SP509 will NOT fit in 2005 heads. SP546 are NOT 1 piece plugs, they are improved and reinforced 2 piece. The only 1 piece plugs for 2005 heads are Champion, Brisk, or E3, none of which I'd recommend.
2004 - mid 2008: SP546 with DG511 cops.
Mid-2008 - end of production: SP-509 with DG521 cops.
