Replacing plugs should i replace the boots
Replacing the plugs next week. I have no codes and truck is running fine (05 crew 5.4 93,000). Should I replace the spark plug boots. If so what brand should i get and from where. Price?

I bought a set of Motorcraft COP's from Rock auto for $300, my truck was running fine prior to changing them but there was noticeable difference afterwards...seemed to run smoother and felt like a little power was restored...
