Spark Plug wires

[410225]

Trying to replace plugs and wires. Funny thing is, I went to AC Delco service center to purchase AC Delco wire and they asked me to get the coil stamped number to verify the wires. 9.2" or 10.5" two different kinds.
How are you suppose to know this without taking the coil out to see what is stamped? I have 2004 H2.

they mean the lenth,you can measure it or take one off and bring it to them to match. better still order them from Summit raceing and get the Summit branded ones made by Taylor ,they are a much better wire for less money . all you will need is some dieltric greese to install them .

Would you happen to know what kind I have to order?

Hey, let me know which size you need. I have a set that I pulled off my H2 when it had very low mileage, as I swapped them out for aftermarket type with higher heat resistance when I added new exhaust headers.

You can have them for a third of what new cost + shipping...

I have the Delco part#. I was referring to the Taylor wire. If the price is not much different, I rather go with Taylor than Delco.
