ACDelco 748G Spark Plug Wire Kit

This Wire Set for Chevy 7.4 Engine works much better than the generic replacements because it incorporates a coiling of a copper wire around the the core element to better transmission of the high voltage spark to the spark plugs. the higher price is justified because if you don't do this some of the spark plugs will miss with the bargain wires.

Also some "experts" claim that there is no gain in gas mileage by buying the higher quality wires. But it only follows logic--if you capture a stronger and better spark the ONLY result is going to be better gas mileage. Also the insulation is much better in AC Delco wires where the cheap wires I had, shorted to ground.
