So I'm looking to buy a new set of spark plug wires before I fire this thing. I have the delphi round coil with heat sink and an old set of 7mm truck wires with like 60k on them. I ohm tested three wires and had a total of 80 ohm difference between them.

I made the mistake of looking up wires for the LS motor and you can spend $40-$240 on a set. 7mm-8.5mm

What is everyone using?

 

Msd 8.5's

 

Firecore50

 

Belden, Taylor, AC

I don't use low resistance wires because high voltage does not behave the same as low voltage and low resistance wires can cause electrical interference problems.

 

This. And only this.

 

Firecore x3

 

Actually granetelli zero ohm wires are really good

 

Firecore50 if you can budget it. Msd if not.

 

I'm using the MSD wires. No problems thus far.

 

I've gone 163mph on stock GM wires.....

 

You can say that about a lot of parts now can't ya?

 

I also use them. Costly though....

 

Firecore50...

 

Msd took number 2 spot above, so it's very obviously the budget wire to go to.

 

I've used stock, Taylor, and MSD (which I am using now). Honestly they all worked fine but I was not ringing out the last one or two hp out of the engines either. Biggest thing, proper length and boot selection so you don't have a wire that develops a break from being improper for the application. On my latest build I am using the MSD wires and pretty happy with them (especially for the price).
