New Spark Plugs
So I'm fixing to replace the sparkplugs and boots on my F150 but I'm noticing a lot of vendors are not selling the SP-534 anymore. Seems to have been replaced with SP-580 but I can't find any feedback or information on them. Anyone familiar with these new plugs and what the gap should be for a stock 2012 F150 FX4 3.5L Ecoboost?

I have the SP-580's in my EB. The 534's have been superceded with the 580's. I recall the gap should be somewhere around .030". I stuck a feeler in there and all of my 580's were pretty close so i tossed them in as-is and theyve been great, especially for my fuel economy.

Thanks for the reply.
Yea I ended up just tossing them in and everything worked great. Mine were all gapped at .031 except for 1 which was at .030 so I just adjusted it to .031. Didn't find much info on the gap except at Stage3 which mentioned to use between .030 - .032.
