"New" MSD Direct Fit Spark Plug wire set for Mercruiser 496HO, 496MAG, and 8.1L Standard Replaces #84-881698, 8M0117678

This MSD spark plug wire set has been custom built to replace the stock inferior OEM wire set found on Mercruiser's 8.1L 496 series of engines. Each spark plug wire is manufactured from MSD 8.5MM Helicore performance wire and provides 10X the spark energy of OEM wire sets. By delivering more spark to the spark plug efficiency and performance are achieved. Here's an example of how powerful these wires are. Multi-angle Spark Plug boots and terminals installed adjustable from 180 to 45 degrees to tailor fit perfectly for Marine Exhaust System and headers applications.

Independent testing of the Custom MSD wire vs the Mercruiser OEM wire showed nearly a 400% increase of energy transmission to the spark plug....Testing of two wires of identical lengths, identical temperature, identical ends...
