im looking at a buncha different brands of spark plug wire for my ls crx and im wondering if the msd wires really make a difference, costing $85, compared to ngk, or even stock wires. what is the difference as you go up in price?

 

NGK/OEM wires are perfectly fine. Don't bother with anything else (especially if it's more expensive).

 

I second that. As for the difference in price, marketing, and possibly more material (insulation). I bought a set of aftermarkets for my '90 Si a few years back when I owned it. Out of curiosity I did an ohm meter check on the new verses the old wires. The new ones were out of spec. Since the old OEM wires were still clean and supple, I kept them in service and returned the new ones.
