Greetings all,
I need to change my plugs and wires. I looked at the Motorcraft website and found four different plugs that will work, but I'm not sure which one of them to use. Here are the four choices: AGSF22FM, AGSF22FMF6, AGSF22PPM, and AGSF22PPMF6. Thanks for your help.

My friend, the way I went about getting plugs for my 98 4.0L SOCH was to go to auto parts stores' web sites and getting info. I ended up going to AutoZone and buying 6 plugs...they are MotorCraft double platinums...only use these plugs or you will have problems. They are about $6 a piece, and I hear they are the same cost at the dealer. For wires, I bought them at PepBoys for about $40, which is way less than the dealer charges for wires, and they work great. As far as exact stock number for plugs, I can't help you. But AutoZone should be able to pull up the right plug...they are the only ones I know of that carry MotorCraft plugs. I hope this helps.

 

Whatever you put in, make sure you check the gap and use anti-seize...

 

I always get mine at Wally World... just use the handy dandy little computer they have hanging in the spark plug isle. Choose between the brands then just find the pack. I then check the gap on them just to make sure (All of the 4.0L OHV's, the 4.0L SOHC's, and the 5.0L V8 share the same gap. Its .054)
I've used Bosch Platinums and Double Plats, no dif except in price.
