Hey everyone, im running a 91 octane tune on my 2.3 n i just put in a brand new set of motorcraft plugs n it was running like damn perfect a couple days n now when im gettin on it in second i can hear it pre detonating im almost positive...

Long story short i need to know what other plugs would work in place of the motorcraft ones? When i changed em back when i first got the car i did like autolights, bosch n those all sucked....any suggestions would be great thanks
