Hi Guys
I was in a big hurry to get spark plugs for the weekend, now they have arrived, I realized they are not the same numbers as what came out last time I changed them. “AGSF32N
SP-413.

I should have kept looking for AGSF32PM SP-493, they were in the motor last time I changed them.

Please can anyone tell me if they are hotter or colder or what the difference will be.
Always appreciate help I get here.

Same heat range, they are nickel-alloy instead of platinum. I am not sure of the wear on the nickel electrode plugs versus platinum, but it likely isn't as long. Motorcraft sells these longer life than copper plugs.

If longevity isn't important to you, these are okay to use. As in they won't last as long as 100,000 platinums, but will last longer than 20,000 coppers.

Hi Bangster,
Thanks very much, I will go ahead and use them. You are right I don’t leave the plugs in for 100,000.Will see if I can get 50,000 out of them. As you probably know gasoline has hit $4.15 a gallon here, so I will be opening up the plug gaps to .065” and fitting “sultans of spark” coils in an attempt to improve MPG.
Mileage now is 105,000.
PS, I see you are up to 86 today,you must know your AC system inside out.

Those plugs will easily last 50k miles. I'd use them and not worry.
