Distributor Cap for 1989-1991 Peugeot 405 - Standard Ignition DU-425

Help deliver ignition voltage to each spark plug wire in firing order with the Standard Ignition Distributor Cap DU-425. It is listed as a replacement for the 1989-1991 Peugeot 405. See the "Vehicles it fits" section for engine details.

A distributor cap sits over the rotor. As the rotor turns beneath it, the cap carries the high-voltage spark from the coil to the correct plug wire. Standard builds its distributor caps on decades of research and development:

• Quality control: Standard is a global manufacturer of original equipment ignition products. It maintains complete quality control through the manufacturing process, from componentry to finished product.
• Cap material: Made of high dielectric strength, glass/mineral reinforced polyester resin. The material is designed for less carbon tracking and greater resistance to electrical breakdown.
• RFI resistors: Used where specified. They are intended to suppress radio static and potential ECU-damaging spikes.
• Terminals: Solid brass terminals are used where available. They are designed to make better connections and to resist electrical pitting and corrosion.

Signs a distributor cap may need replacing: cracks or carbon tracks inside the cap, worn or corroded terminals, misfires, hard starting, or rough running. Other ignition faults can cause the same symptoms, so diagnose the system before replacing parts. If a worn cap is the cause, the DU-425 replaces it. Inspect the rotor at the same time.
