Marine Spark Plug Wires

Shop at Marine Parts Source when you need spark plug wire kits for an inboard or inboard/outboard engine. Most boat enthusiasts know they need to periodically replace the spark plugs, but the wires are just as important for good ignition system performance. Worn-out or broken wires can cause problems like difficulty starting the engine, rough idling and excess fuel usage. Get these replacement spark plug wires for scheduled maintenance or at the first sign of trouble to keep up your engine’s performance.

We have OEM and aftermarket wire sets for all leading boat engine manufacturers, including Crusader, MerCruiser, Volvo Penta, Chris Craft and Indmar. Select a wiring product to see a list of which engines and ignition systems it is compatible with. Even if you only need to replace one or two wires, ordering a full set will have you prepared in case of future issues. Many other ignition parts are available with fast shipping from warehouses across the U.S.
