Spark plug question 99 3.0 FFV engine
Can anybody give me info on this engine. I've read the left bank is different than the right bank. I pulled one plug from the left bank and it was a Motorcraft AGSF 32N thats the only one I pulled at the time. I'm wanting to know what would be the best plug for this engine that I could possibly put in both banks. Iridium or double platinum or something different. I'm having some studdering issues going down the road and was thinking about changing them out. I just bought the truck about a month ago. Thanks for any info anyone could give me.

Go to the Motorcraft web site & enter your vehicles particulars & look up the latest specification Motorcraft plug for your flex fuel engine. If you use E-85, you'll want to be mindful to use the specified heat range plug that Ford spcifies, as the vehicles fuel sensor has the computer adjust the air/fuel ratio for the amount/% of Ethanol the fuel contains, so sprak plug heat range is important for your flex fuel set up.
IMO the correct heat range finewire iridium enhanced center electrode plug is a good investment, as its spark gap will remain in spec longer & the finewire center electrode will likely offer up quicker year round starts, at least it has for my vehicles & the spark gap is remaining in spec longer too.
It's said that Ford has Autolite build its Motorcraft plugs & Autolite has a good rebate going on their finewire plugs if you choose to cross reference them.
Here is a link to more spark plug thoughts in a mini spark plug tutorial that might be helpful in thinking through your spark plug choice.
