Upgrading my plug wires to NGK's. I have looked everywhere on here for a part number to use but can't find anything. I want to run a larger than stock size like most people here but what do I tell the guy behind the counter at the parts store. Most of them just look up the truck year and say that is the wire you need. Right now I have a set from my 81 Corolla on my truck and they work fine but I can't stand that round valve cover boot on the wire.

 

interesting... did you try ngk's website?

 

I tried there first but it only give me the OEM wires and no mm specs for the wires.

Wire Set Part No. Stock No.
Wire Set TX59 ¹ 4417

 

from what ive experianced the OEM wires they use are bigger then stock... I have em on my truck right now, ill get a pic when I go outside. The stockers are tiny 6mm or something like that wires, the ngk ones are like8-10mm
