Found something that doesnt work with a 11psi Blower and E85 - XOR12YS Brisk Racing Plugs - Flat Melted down and within a day on the dyno lost 3 from Meltdown misfire - Made More Power with OEM and thankfully I didnt throw away the good old Ford ones - so be careful when looking at an $19 plug based on Performance - Yes, for the skepics - I called them and discussed the application first and took the plug they suggested - based on boost, power, and fuel - Silver Racing Plugs - No Go for a 105 octane green machine -
