Help regulate your charging system's output with the Standard Ignition Voltage Regulator VR-422, the 240SX voltage regulator built as a direct-fit replacement for the 1989-1990 Nissan 240SX and the 1986-1988 Nissan 200SX. A voltage regulator is designed to control the alternator's output so the battery and electrical system receive a steady charging voltage.

  • Quality control from start to finish: Standard Ignition is a global manufacturer of original equipment ignition products and keeps complete quality control over the manufacturing process, from componentry through the finished product.
  • Epoxy-encapsulated PC board: Standard's electronic voltage regulator PC boards are sealed in epoxy for improved performance and resistance to failure that vibration and corroded electrical connections can cause.
  • Premium components: Premium components and Standard's own manufactured circuit board are designed for precise operation, reliability and extra durability for a longer service life.
  • High-grade materials: Standard's starting and charging system products use high-grade materials for extended service life.
