Route coil high voltage to the right spark plug in firing order with the Standard Ignition Distributor Cap JH-187. It installs as a direct-fit replacement for the 1992-1996 Mitsubishi Diamante, the 1996 Dodge Stealth, and the 1997-1999 Mitsubishi 3000GT — see the Buyer's Guide tab for engine-level fitment.

  • Molded for dielectric strength: built from glass/mineral-reinforced polyester resin with high dielectric strength for less carbon tracking and greater resistance to electrical breakdown.
  • Solid brass terminals (where available): designed to make better connections with greater resistance to electrical pitting and corrosion.
  • RFI resistors (where specified): intended to suppress radio static and help limit voltage spikes that can damage the ECU.
  • OE-focused quality control: from a global manufacturer of original-equipment ignition products, with quality control maintained from componentry through the finished part.

A distributor cap distributes secondary voltage from the coil to each cylinder's plug wire. Signs it may need replacing include hard starting, misfires, rough running, or stalling. If a cracked, carbon-tracked, or corroded cap is the cause, this replaces it.
