i never thought of this before, would this effect my new motor in my truck that i swapped since it is a 2003 5.4l 2v ? it had originally the cop ignition black boots before i swapped to coil system. i have not changed them as of yet since i am waiting for my tunes first. But shortly there after this is since i do not know when or if they were ever changed in this vehicle originally. it had only 38,000 km on engine when i bought it a month ago
