Mallory Marine Promaster Spark Plug Wires are made with only the best components. They have a tightly wound fiberglass braid that forms a permanent bond between the EPDM inner layer and the outer silicone jacket to increase wire strength and eliminate terminal pull-off.
Ultra low resistance spiral core delivers high-energy output for maximum spark at the plug
Excellent RFI/EMI suppression for even the most sensitive high-tech onboard electronics
8mm ozone-resistant blue silicone jackets repel water, oil, grease & fuel and withstand up to 500°
Custom fit for your specific marine application and ready to install
