A buddy of mine has a 98 Z(ls1) and was wondering what plugs wires to run on the car. Mods consist of NONE being the fact that its completely stock. What would be the best wires to run on this car to spark ti up a little bit?? Any info would be great

 

NGK TR55 plugs. Any good aftermarket wire will do. I have Taylor Thundervolt 10mm wires on mine.

 

I am the MSD 8.5 s on my car

 

MSD wires ohm out the best of any LS1 wire offered. They are also the cheapest....so MSD is a good choice.

However...he will see NO gains from a plug wire change unless one of the stock wires is damaged.

 

Doesn't matter how big the wires are unless the ignition system is upgraded..the factory coils push the same spark if you have 8mm or 10mm wires

 

wires with less resistance will allow more of that voltage to get to the plugs.

 

Remember that the Ls1 has one coil per cylinder. And like Half Fast said less ohms of resistance means more voltage at the plug.

 

And what a big pain in the ass it is to do plugs and wires on a 4th gen! I'd say leave it stock unless he plans on doing some other stuff to the car.

 

Hes got plans for doing something with it. His previous car was a mildly modified LT1. I think he mentioned something about the LS6 mani being first.

 

you dont really need 10mm wires... go with MSD 8.5mm.. and with the LS1, changing the ignition means changing all 8 coil packs which is like 200 bucks a pop for aftermarket ones...not worth the cash....just make sure the spark plugs are gapped right and make sure they are long enough..
