With its aerodynamic styling and sporty handling, your Cougar was made to move with ease. It all starts with your spark plug, however, so be confident with high-quality Mercury Cougar spark plug wires from AutoZone. In addition to starting your vehicle, these wires ensure that you avoid stalling, rough surges and poor fuel economy. Visit a local AutoZone to speak with our helpful staff about your ignition process and ask about our Loan-a-Tool program, if you like to do your own auto work. You can even shop with us online and benefit from Free Shipping on any purchase of $75 or more.
