I can' say enough about the Motorcraft Sp542 plus gapped at .025. My truck and tune love it. A few others I know love it as well. Worth a try. It' the same plug that the 2.7L uses from factory. And it' a step colder plug for the 3.5L...I've got the 3.5L

Did y'all replace the boots? I see the video fordtechmakuloco recommended it, especially if there is carbon tracking.
I picked up sp534 spark plugs in the USA (O' riellys 50% cheaper than Canada.)
Any Canadian brothers bought boots up here? Best option (I'll go back across the line if its far cheaper like the plugs were)
Also the plugs I bought were gapped at .030 except one which was .028 (I adjusted it to 0.030 without touching the electrode) which surprised me (thought I'd have to gap them all.)
