Keep high-voltage spark routing to the right cylinder with the ThunderSpark Distributor Rotor 926-1030. This rotor drops in as a direct-fit replacement for the 1988-1989 Mazda 323, the 1988 and 1990-1992 Mazda 626, and the 1991-1994 Mercury Capri — see the "Vehicles it fits" section for engine-level details. It transfers high-voltage current from the ignition coil to the correct terminal on the distributor cap, helping maintain accurate spark timing for each engine cylinder.
- Spark distribution: Delivers high-voltage current from the ignition coil to the distributor cap terminals for proper alignment and spark timing.
- High-dielectric materials: Designed to resist arcing and heat degradation under demanding operating conditions.
- Corrosion-resistant contact surface: Engineered to support reliable conductivity and consistent output.
- OE-matched design: Built to OE fit, form, and function standards for the listed applications.
Signs this rotor may need replacing include hard starting, misfires, or engine hesitation. If a worn or arced distributor rotor is the cause, installing this ThunderSpark rotor replaces it — diagnose the ignition system first, since these symptoms can have other causes.
