SP433 vs AGSF32WM Dimensions & Markings

[pantheroc]

Are there dimensional spec differences between SP433 and AGSF32WM for length of threads? Anyone have measurements?

I'm assuming I received a set of longer(?) AGSF32WM's in a box marked both SP433 and AGSF32WM.

I measured 16mm from bottom of taper to flat surface at end of plug.

Are the current SP433s marked with "SP433" or still marked with "AGSF32WM"?

Not sure exactly what you're asking, Jerry...the two plugs you listed are identical...Ford changed over from the longer numbering system to the shorter "SP" numbering several years ago.

If you're concerned about thread length, only the factory installed plugs were half-thread. All service replacement plugs are full-thread.

My concern was thread length. I was trying to determine if markings and dimensions indicated I bought a set that may not be the ones I want. You cleared it up for me. Thanks
