Sp542 will work also, but not really needed with 93 fuel. Shell and Exxon are currently the top performers on my list.

No harm in gapping to 0.028, stock or not, but i dont like having to gap modern plugs.  0.030 is stock on 534s IIRC.
2007 Ford Edge SEL, Powerstop F/R Brake Kit, TXT LED 6000K Lo & Hi Beams, W16W LED Reverse Bulbs, 3BSpec 2.5w Map Lights, 5W Cree rear dome lights, 5W Cree cargo light, DTBL LED Taillights

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!
