Has anyone replaced their spark plug wires with MSD Super Conductor 8.5mm wires? How do you rate these wires? Is it really worth the money? Will it make the car run any better?

I havent tried them myself, but if you email me @ suprageezer@aol.com I can tell you how to save a bundle on your purchase of them.

hey suprageezer how do you save a bundle?

Ditto, put that shit up so everyone can save a bundle. MK3ers need to stick together.

Okay here goes. Some folks aint gonna like this BUT. I have restored a few cars and bought most of the parts over the internet. Here's what I do, First I score the manufacturers part number of the part I want, then I go straight to summitracing.com look in the manufacturers list and if they Rep that manufaturer Im 90% sure I'm gonna save some dough. Try looking up your MSD wires there, and for the heck of it try looking up the Fluidyne Radiators all the supra sites sell. I have and Summit can save you some money. Everytime I check Summit they are Reppen more and more Tuner parts so if you wanna keep getten your stuff at a reasonable price and not make the some of these supra parts store owners retirement material after the first year in business try Summit and write them if they dont Rep the manufacturer of what your looking for and maybe they'll end reppen them too.

and summit has my stuff at my door the next fricken day or two. they must be close, but still awsome service..

Oh yea, Summit rocks. I got my NGK Iridiums from there WAAAY cheaper than anywhere else. Got my electric fan there cheaper too. I always check Summit first. You def. need the part number because sometimes they dont list the part when you search by car but if you search the part # you can find it.

Cool, now on Spark plugs I only go with Nippon Denso, for my Supra, Dodge van, and all my dirt bikes. I get those online also at sparkplugs.com.
