Keep high-voltage spark reaching the right cylinder at the right moment with the Standard Ignition Distributor Rotor DU-315. It is a direct-fit replacement for the 1985-1987 Renault Alliance and the 1985-1986 Renault Encore. See the "Vehicles it fits" section for engine details.
The rotor turns with the distributor shaft inside the cap and carries ignition-coil voltage across to each spark-plug terminal in firing order. Standard Ignition is a global manufacturer of original equipment ignition products and maintains quality control throughout manufacturing, from componentry to the finished product.
- Dielectric alkyd body: high-grade dielectric strength alkyd resists dirt sticking to it, which helps decrease carbon tracking for extended service life.
- Solid brass segments: designed for better conductivity and a higher-voltage spark to the plugs.
- Shaft retention clips: used where the application requires them, for proper fit and performance.
- Decades of development: draws on Standard Ignition's decades of research and development in distributor caps and rotors.
Signs a rotor may need replacing include misfires, hard starting, rough running, or a burned, eroded or carbon-tracked tip on inspection. If a worn rotor is the cause, the DU-315 replaces it. Inspect the distributor cap at the same time, since the two parts work together.

Frequently Asked Questions
Which vehicles does the Standard Ignition DU-315 fit?
It is listed for the 1985-1987 Renault Alliance and the 1985-1986 Renault Encore. Check the "Vehicles it fits" section for engine details.
What does a distributor rotor do?
It spins with the distributor shaft and transfers high voltage from the coil terminal in the cap to each spark-plug terminal in turn, so each cylinder gets its spark in firing order.
What are the signs of a worn distributor rotor?
Possible signs include misfires, hard starting, rough running, or a burned, eroded or carbon-tracked rotor tip. Diagnose the ignition system first, because other parts can cause the same symptoms.
What is the DU-315 rotor made of?
Standard Ignition specifies a high-grade dielectric strength alkyd that resists dirt sticking, which helps decrease carbon tracking. It also uses solid brass segments for better conductivity.
Should I check the distributor cap when replacing the rotor?
Yes. The rotor tip and the cap terminals work together, so inspect the cap for cracks, carbon tracks or worn terminals when you install the new rotor.
