If memory serves me correctly, both Autozone and the Ford dealer wanted to sell me the 22FS plugs, however it may have been a different series. Im still with the 32fm's because Ford wanted $8 a plug and Autozone was 'fresh out' of whatever it was they were reccomending.
Now that I know these will at least work, I'm going to put them in and be fine with them wearing out soon. I will order up a set of what's already in there and replace these in the future.
I really think 22FS plugs are whats in there tho...
Thanks for your help.
