The spark plug wires bring the spark to the plugs. If one of the wires has a short in it, replacing the entire set is the best course of action because it can be difficult to spot exactly which wire is shorted, since - in many cases - not all damage to the wires is visible. The spark plug wires are complete sets to match the number of plugs on your engine. The Accel 300+ Thundersport spark plug wire set resists the damage from the high heat of the engine as well as chemicals or moisture the wires may be exposed to. Accel has been making parts like spark plug wire sets for over a quarter of a century. The knowledge and experience gained over this time has allowed Accel to make products that can withstand the rigors of a daily commute through traffic or the stresses of the raceway. The reliability and high value that come with a vehicle argue for always buying replacement and aftermarket parts of the same level of value; high-quality parts don't have to cost an arm and a leg. Top-quality replacement parts are what owners need to keep your vehicle in great condition however harsh the conditions.
