Blue NGK Plug wires switch help?

[TheDurk]

I think mine are original wires with 286K. :laugh: I have at least 120K on them so they are over due.

Factory wires are Sumitomo and have the year of manufacture on the wire insulation. So it's easy to tell.

just confirmed mine are original and i've got almost 205K miles. is there any benefit to changing them if it's running fine?? just preventative?

Mine were originals with 267k. Dated 1996. Still seemed to work fine hahaha.

Just put a set of Denso wires and boots on along with NGK plugs. Went with Denso wires because I dont like blue under the hood for some reason and Denso is a division of Toyota anyways. Idles smooooth now.
