There are a lot of critical systems in your engine, and one of the most neglected is the ignition system. The ignition system generates, carries, and distributes the spark that allows the fuel to burn, generating the power. It is an electrical system, and like any electrical system, a small problem anywhere reduces the overall performance significantly. If you want to get the most out of every component of your ignition system, than you need to use only high quality wires to carry the voltage. Accel spark plug wires are a great way to maximize the effectiveness of your spark. Your factory spark plug wires are designed to be cheap and economical, and not for performance or serious longevity. Accel spark plug wires are resistant to spark loss, and they use only quality components to ensure the best transmission of the voltage. They are heat resistant, so they will not break down, and the insulation keeps those tens of thousands of volts right where they need to be. If you have an older car, your spark plug wires may appear cosmetically fine, but they can be deteriorating from the inside out. if you replace them with Accel spark plug wires, you can see some serious gains in performance. Not only will you be replacing worn components with new, but you will also be replacing restrictive factory wiring with high quality performance wiring from an industry leader.
