What It Helps Address

  • Weak or inconsistent spark output
  • Hard starting caused by ignition coil wear
  • Misfire conditions related to coil degradation
  • Rough idle from unstable ignition performance
  • Loss of ignition reliability in older Toyota systems

Installation Notes and Tips

Confirm the vehicle year, model, and ignition configuration before installation. The 1981-1982 Toyota Tercel listing is for Electronic Ignition, Export Only, so match that note exactly. Inspect coil connectors, wiring, and mounting points for corrosion or damage before installing the replacement coil. Use the part number C-646 and the vehicle’s original coil specifications to verify fitment.
