I just got a 2010 XLT with just over 100,000 miles. Looks and drives great and am pretty pleased with it. I know it's time for plugs and it sounds like I don't need to replace coils unless it throws an error. Seems a little sluggish when cold. Looks like it needs Motorcraft SP509 plugs, and I will replace boots at the same time after reading the forum. What boots do I need? I see some straight ones, and angled ones. Would these work?

or should I look for something different?
