But these spark plugs are agsf not agrf I heard the agrf is resistor but the others not..
And why I can't find the agrf22pp anywhere?!

stick with Motorcraft or Autolite plugs gaped to .054 as mentioned. Platinum, Double Platinum or Iridium (good/better/best). other brands have been known to cause problems in these engines, especially Bosch brand.

Resistor type plugs are designed to suppress ignition noise from computer and entertainment systems. (See pages 8-9)

A= Thread Diameter
G= Reach
S= Special Resistor
F= Finewire Platinum Center Electrode

You are fine, the wires have resistance incorporated.
I would recommend a fine wire spark plug, best ones in my opinion are NGK Laser Iridium because they have platinum disk on the ground electrode.

Plug Gap .054 vs .040

tagging on here since the gap is stated to be at .054 but the original Autolite AP103 plugs come at .040...saw a couple of strings on increasing to .054 and getting mixed signals

'01 Sport Trac 4.0L "E" model -
having with load "missing" issues -

Coil is to be replaced this week - just cause
Plugs are new gapped to .040
Wires are new

thoughts on GAP??
