Full 10.5mm (stock is 7mm) spiral core performance wire sets ready to install. Long enough to fit underneath rather than across the valve covers. A stock black wire is shown in the photo which is stock OEM wire size.
This wire set not only looks impressive, but allows widening the spark plug gaps to .060 when using our 65000 volt HEI distributors. These wires are necessary because of the increased resistance when increasing the gap this much, and power and fuel economy will be the net advantage. AAA MARINE PARTS WHOLESALE printed on wires.
