Spark Plug Wire

Connecting the spark plug to the distributor and some ignition coil types is the spark plug wire. Its job is to deliver voltage to the spark plug without interference from other electrical components and with as little resistance as possible to provide the best spark.

When selecting the correct set of spark plug wires, it's important to match them to the year, make, and model of your engine. If doing a custom ignition, spark plug wire length, diameter, and boot type are equally important.

JEGS offers the best selection of spark plugs and wires for your car, truck, or race vehicle from brands such as Walker Products, Taylor, Granatelli, NGK, Autolite, Champion, and more. Each set of spark plug wires is made from high-quality materials and assembly that will ensure long service life and performance you need from your engine.
