With age, we have seen the coil pack connectors become brittle , and the retainers fail. ScienceofSpeed is proud to offer new replacement connectors with retainers, terminals and seals included. You can replace only the connector if you like. In order to replace the seals, you will need a double barrel roll crimper. Price is for 1 vehicle worth, or a quantity of 4 connectors with seals and terminals.
