Help keep high-voltage spark reaching every cylinder with the Standard Ignition Distributor Cap DU-420. It is listed for the 1975-1979 FIAT 128 and the 1985-1987 PEUGEOT 505. See the Buyer's Guide tab for engine details.

A distributor cap covers the distributor. Working with the rotor, it routes the ignition coil's high-voltage output to each spark plug wire terminal. Over time a cap can crack, develop carbon tracks or corrode at its terminals. Misfires, hard starting and rough running are signs this part may need replacing, though those symptoms can have other causes.

  • Quality control: Standard Ignition is a global manufacturer of original equipment ignition products. It maintains complete quality control throughout manufacturing, from componentry to finished product, and draws on decades of research and development.
  • Cap material: Made of high dielectric strength, glass/mineral reinforced polyester resin. It is intended to reduce carbon tracking and resist electrical breakdown.
  • RFI resistors (where specified): Designed to help suppress radio static and potential ECU-damaging spikes.
  • Solid brass terminals (where available): Intended to make better connections and resist electrical pitting and corrosion.
