    Choosing ignition and electrical parts

    A strong spark and clean power make an engine start easily and run smoothly. If your engine misfires, hesitates or is hard to start, the spark plugs, wires and coil or distributor are the usual place to start.

    Spark plugs are chosen for the engine, the heat range and the gap. Use the plug type your engine calls for, and set the gap to the specification. Iridium and platinum plugs last longer than standard copper plugs, while copper plugs are still common on older and high-boost engines.

    Spark plug wires carry the spark, so replace them as a set and keep them routed away from hot exhaust parts. For classic cars and builds, a complete wiring harness is often a better fix than repairing old, brittle wiring one piece at a time.

    Batteries should match the size, terminal position and cold-cranking amps your vehicle needs. Brands we carry in this category include MSD Ignition, NGK, Moroso, ACCEL, Painless Wiring, Proform, American Autowire and Odyssey.

    Common questions

    How often should I replace spark plugs?

    It depends on the plug type and the engine. Follow the interval in your owner's manual, and replace them sooner if you notice misfires or poor fuel economy.
