Just noticed that my newly acquired CSVT has plug wires that have 1998 on them....Is it time for new ones already or what? My question is, what seems to be the best and most reliable wires out there??? Also, are people replacing PCV valves with the same ones? I only ask because on my 2001 Lightning we could use the new Cobras 1 way PCV to stop oil in our intakes(TB's and intercoolers). Any input??
