• Quality control from start to finish: Standard Ignition is a global manufacturer of original equipment ignition products. It keeps quality control in-house, from the componentry through to the finished product.
• Decades of development: Standard draws on decades of research and development in its distributor caps and rotors.
• High dielectric strength housing: The cap is made of a high dielectric strength, glass/mineral reinforced polyester resin. This material is designed to reduce carbon tracking and to resist electrical breakdown.

The distributor cap sits over the rotor. As the rotor turns, the cap's terminals pass current from the ignition coil to each spark plug wire in firing order.

Over time a cap can crack, collect moisture, develop carbon tracks or wear and corrode at its terminals. Any of these may be a sign that it needs replacing. Misfires, rough running or hard starting can also have other ignition or fuel-system causes, so diagnose the cause before replacing parts.
