The spark plug wires on your car, truck, van, or SUV are responsible for harnessing tens of thousands of volts and delivering that juice to the spark plugs every time, without fail. As spark plug wires age, though, the insulation gets brittle and the core develops cracks: Not good news. Any breakdown in the spark plug wire gives the electricity somewhere else to go, and the result is engine misfiring, fouled spark plugs, and rough running. The problem is, spark plug wire problems can be hard to detect, since spark plug wire insulation and core problems can hide just below the spark plug wire surface. A new set of spark plug wires will restore the ignition performance of your car, truck, van, or SUV. We stock OE replacement spark plug wires for most import and domestic applications. Looking for something that can deliver a little more spark? We also have high performance spark plug wires from Accel and Taylor, among others. Accel spark plug wires and Taylor spark plug wires improve conductivity on street or race machines. With thick silicone spark plug wire jackets and excellent RF suppression, our Accel and Taylor high-performance spark plug wires can deliver a hotter spark for better combustion, and that means more power and torque to the pavement. Don't forget, when replacing spark plug wires or installing high-performance spark plug wires, check the other ignition system components as well. We also stock distributor caps, ignition rotors, ignition modules, and spark plugs for most vehicles, allowing you to do a full ignition system tune up.
