Is there any real gains when using these? they were about 80$ on speed-eng.com

 

If your present wires are in good shape and its a "stockish" engine, there will be no advantage in going to the MSD 8.5mm SuperConductors. If you have a high HP/power adder setup, and a high voltage ignition system, the MSD's will provide better performance.

Might want to add a "signature" with basic info about your car.... year, model, engine, trans and any major mods.

 

Well i have about 45,000 miles on my car, and am soon going to be putting some pacesetter longtubes on. Ive heard most people replace plugs/wires while they are at it.
