It is part of Sierra's MAGFORCE line of ignition wires, engineered to be \"electronics friendly\" so it protects onboard electronic devices and electronic engine controls from RFI (radio frequency interference) and EMI (electromagnetic interference) while still delivering the maximum amount of voltage to the spark plug. The metallic copper core construction is designed to carry current efficiently and consistently for reliable ignition performance on the water.\u003c\/p\u003e\u003cp\u003eEach wire uses an exact fit design intended for straightforward installation and years of trouble-free service, making it a practical choice for routine ignition maintenance or replacing worn, cracked, or high-resistance spark plug wires. Because these wires are sold per package of 5 at a fixed 10 inch length, they suit engines and configurations that call for that specific wire length; Sierra also offers this same wire in a 9 inch version (18-5227-1) and a 22 inch version (18-5229-9-1) for applications requiring a different length.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-5230-9-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Gauge:\u003c\/strong\u003e 7mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore Material:\u003c\/strong\u003e Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Type:\u003c\/strong\u003e Metallic core wire\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.53 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgnition System Feature:\u003c\/strong\u003e Electronics friendly, RFI\/EMI protection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eHow long is the Sierra 18-5230-9-1 spark plug wire?\u003c\/strong\u003e The 18-5230-9-1 spark plug wire measures 10 inches in length, which is the fixed length for this specific part number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many wires come in a package?\u003c\/strong\u003e The 18-5230-9-1 is sold as a package of 5 spark plug wires, not as a single wire.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the wire made of?\u003c\/strong\u003e This spark plug wire is built with 7mm copper core metallic wire, part of Sierra's metallic core wire construction.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat makes this different from a standard spark plug wire?\u003c\/strong\u003e The 18-5230-9-1 is part of Sierra's MAGFORCE ignition wire line, which is designed to be electronics friendly, meaning it protects onboard electronic devices and electronic engine controls from RFI and EMI interference while still delivering maximum voltage to the plug.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this wire suitable for a marine ignition system?\u003c\/strong\u003e Yes, the 18-5230-9-1 is designed as a marine ignition system spark plug wire with an exact fit design for easy installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat if I need a longer or shorter wire than 10 inches?\u003c\/strong\u003e Sierra offers the same wire construction in other lengths under different part numbers: 9 inches is part number 18-5227-1, and 22 inches is part number 18-5229-9-1.
