Rotary 7mm Spark Plug Wire 10 Ft Roll Copper Core Black Hypalon Ignition Cable #8775.
Restore Maximum Spark Voltage & Eliminate Ignition Leakage: 7mm Copper Core Wire
Eliminate weak spark arcs, hard pull-starting, carbon core resistance breakdown, and high-voltage arcing to ground across your small engines and vintage equipment. This Heavy-Duty 7mm Copper Core Spark Plug Wire (Item #8775, 10-Foot Roll) is the professional-grade bulk ignition cable engineered explicitly for small engines, magnetos, vintage tractors, outboard motors, powersports, and commercial outdoor power equipment . Standard automotive carbon-trace suppression wires severely throttle spark output on small magneto systems, causing intermittent misfires and fuel-fouled plugs.
Manufactured with a multi-strand tinned copper conductor, this 7mm high-tension cable delivers near-zero electrical resistance, ensuring 100% of the coil's output reaches the spark plug gap as a crisp, hot blue arc. The stranded copper conductor is encased in premium Hypalon synthetic rubber insulation , delivering superior dielectric strength that stops high-voltage flashover and corona breakdown. Unlike cheap PVC wire jackets that turn brittle, crack under engine heat, and melt when exposed to fuel or exhaust headers, Hypalon remains supple, flexible, and completely resistant to engine oil, gasoline splash, high ozone, and UV sunlight.
Supplied as a 10-foot continuous coil (Item #8775) , this bulk length allows mechanics to cut custom-length ignition leads for multi-cylinder engines, chainsaw and blower repowers, vintage tractor restorations, and magneto rebuilds without paying dealership markup for pre-terminated leads.
Why This 7mm Hypalon Copper Core Spark Plug Wire is the Mechanic's Standard:
Pure Multi-Strand Copper Conductor: Provides near-zero electrical resistance to deliver maximum spark energy from magnetos and low-output coils.
Heavy-Duty Hypalon Jacket: Resists temperatures up to 300°F (149°C), remaining pliable without hardening, dry-rotting, or cracking over years of service.
Total Chemical & Ozone Immunity: Impervious to spilled gasoline, 2-stroke oil mix, hydraulic fluid, engine degreasers, and environmental ozone.
Superior Dielectric Flashover Protection: Thick-wall insulation prevents secondary voltage from arcing through the jacket to cylinder fins and shrouds.
10-Foot Continuous Bulk Coil: Cuts cleanly to custom lengths for multiple small engine tune-ups, multi-cylinder restorations, or shop inventory.

Fits walk-behind and zero-turn mowers powered by vintage Briggs & Stratton, Kohler, Tecumseh, and Wisconsin cast-iron engines.
Vintage Farm & Utility Tractors:
Fits Farmall, International Harvester, Ford 8N/9N/NAA, John Deere, Allis Chalmers, Case, and Oliver tractors equipped with magneto or standard distributor ignition.
Powersports & Marine Applications:
Fits vintage motorcycles, ATVs, snowmobiles, personal watercraft, and outboard boat motors (Johnson, Evinrude, Mercury) specifying solid copper core wire.
Universal Application: Ideal for any small engine, stationary power unit, or generator using screw-in coil towers or metal terminal crimps.
🛠️ Pro-Maintenance Tip: Watch the "Screw-In Coil Tower & Terminal Crimp Secret!" Coil Tower Secret: Many small engine ignition coils (like older Stihl, Husqvarna, and Kohler units) feature a threaded internal brass barb inside the coil output tower. Cut the #8775 wire square with sharp wire cutters, apply a dab of dielectric silicone grease to the outer jacket, and thread the wire directly onto the internal screw until it seats firmly against the bottom; this ensures a clean, mechanical bite into the copper strands without damaging the outer insulation. Spark Plug Boot Tip: When installing right-angle spark plug terminals, strip back roughly 1/4" of the Hypalon jacket, fold the bare copper strands over the outer insulation, and crimp the terminal firmly over the folded wire before sliding the boot on.
